This should get you started. You will need to create an account on www.grabcad.com to download it, but it is a FANTASTIC model. I base all of my rail mounted accessories off of it.

If you need some help the the CAD, Getting a prototype fabbed up, or anything like that, let me know. I've got some contacts.
I'm sorry about your buddy. Sounds like he and I would have gotten along.
I have a 3D printer. Solidoodle 4. First, this seems a little dumb. You can go to http://thingiverse.com/ and http://grabcad.com/ and get many many 3D models, in both STL and more easily customizable STEP formats. Furthermore, I have access to Pro|ENGINEER software (most do not, I understand that...) so I don't need their crap. In homage to one of the comments below, I can design my own dick butt cookie cutter. But finally, again, I noticed the thing about the cookie cutter. One of the nurses at the clinic I go to for chemo is a Mickey Mouse freak. So I found a Mickey Mouse cookie cutter online, and printed it for her... but being the good engineer that I am, I did some research... while ABS plastic is generally considered food safe, to be sure, you have to get a cert. from the material manufacturer... not all ABS is food safe. Also, there is another aspect to food safety, which involves a porous surface, and the ability to retain bacteria through washings... 3D printers have HIGHLY porous surfaces, and as such, nothing coming off a 3D printer that uses fused filament technology can be considered food safe... do I smell the warm, bakey goodness of a lawsuit in the works?
Well this is a repost and last time I saw this the top post described why this was unimpressive. The commentor mentioned all the things in the video were from hobbyist kits, and that the video is the result of older generation (untech saavy) fooling themselves that they found some super nerd that was going to change the future.
EDIT- YOU TOO CAN BE A SUPER GENIUS ELON MUSK WITH THESE TWO ITEMS put model onto usb and then buy the printer

All it is is a model of an iPhone with "noPhone!" text on it. If you don't want to use one of the dozens of STL models you can find online, you can model it yourself in about 15 minutes instead.
- Draw a rectangle with rounded corners
- Extrude
- Bevel Edges
- Use a beveled edge cylinder and rounded end cylinder to do a boolean difference for button & speaker holes
- Add extruded text of your choice
- Save > Print
Here is a great tutorial for modeling gears in Solidworks: http://grabcad.com/questions/tutorial-how-to-model-involute-gears-in-solidworks-and-show-design-intent
I will make one note: this tutorial produces gears that are exactly at their nominal dimensions. Real gears are always slightly undersized to allow the gears to move freely. This tutorial recommends adjusting the center distance to accommodate that, I would recommend adjusting the size of the tooth and keeping the center distance at the nominal center distance to avoid issues when you are modeling all the gears of the transmission. To do that, in step 22 - instead of putting your gear tooth centerline exactly in the nominal center of the tooth, reduce the angle so the tooth is ~0.1mm narrower on the pitch line than it would be if you modeled it nominally. This is roughly the clearance that a real gear would use.
Yes, pitch and pressure angle need to be the same for gears to mesh properly. That should be all you need.
This site has all of the calculations you should need to make the calculations for your gears: http://www.cage-gear.com/spur_gear_calculations.htm The formula for center distance is: C = ((n1 + n2)/2) / Pnd
Not sure. It may have something to do with which gears are used for each speed of the transmission? Are the M gears and the C gears on different planetaries?
EDIT: Forgot a word.
Gorgeous. I don't see the files anywhere yet, but I know Haveblue (the first guy to release a printed AR receiver) has tested a printed 10/22 stock as a rifle and had good results there as well.
It's probably this receiver with standard mail order add-ons applied.
Is it mechanically mated such that you could create an animation or motion study? If your copy of SW has PhotoView how about some sweet renders?
Also, Grabcad would love this.
This is how I would approach this (if had permission to use the logos). Here is a 3d model of a football helmet. Use this website as a reference for logos and the helmet design and render them using keyshot. You would design the labels (logo/graphics whatever)in Photoshop or illustrator to scale and place them on the model. Set the materials/colors to what they need to be and render it in the angle you need.
Dude, you are underestimating the size of this task. You should have no expectation that a polygon file could easily turn into a produced part without a lot of pain.
Save yourself the trouble: http://grabcad.com/library/mq-1-predator-uav
I train others to use SW. but I've found these websites to be of great help! Also, download models off of grabcad in sw form and check out their feature tree and try to replicate their process. (i meant to include solidworker but that site is down) http://www.swtuts.com/ http://grabcad.com/
PM me if you need specific help!
Depends on the scope and project. I'd love to help how I can. There are some reasonably accurate uprights and an NB Steering Rack on GrabCAD.

Another good resource:
Any chance you could post the stl files you used to 3D print this? I've got access to a nice 3D printer and I'd love to try to print a copy.
Edit: nevermind, found it! Also, there's a video of it moving here: http://grabcad.com/library/mobius-gear
i am just trying to be realistic because it feels very off, its 2015, kids aren't going to build homemade volcanoes anymore. You might as well be excited for homemade RC airplane/quadcoptor videos, it's in they same are of skills required. Your misunderstanding of 3D printing being this benevolent extremely difficult matter tops it off, 3D printing got to this level of popularity and popular knowledge because it is SO EASY. you literally just have to download the models off grabcad.com onto usb and plug it in and print. Here is the model then buy the printer, boom you are a super genius, i will come film you and add dramatic music. It just goes to show how behind the times people are, and the overproduction for something like this erked me, it's trying to portray these tech projects as out of reach for the average person
I started with RPi Model B's SolidWorks model, I think it was this one. I then modeled the USB hub roughly. Then I just eyeballed the dimensions roughly so it'd be a snug fit with the components but would still have roughly the same proportions with the original NES. Everything else was just detailing.
The RPi CAD model was really useful for the mounting holes and HDMI output location.
If you have SolidWorks I know there is a trace feature that can create a sketch around a certain color in a jpeg. I imagine it would work well with the black and white contrast...

Hey OP, a quick search on GrabCad showed me a few results of the Pixar lamp.
http://grabcad.com/library?per_page=20&query=pixar
Now i am not sure what program those were made in or the dimensions but i hope it can give you an idea of what you need.
Try Thingiverse or GrabCAD, should have what you need. It depends on your specific printer, but look for .stl files as they are easier to print.
GrabCAD is the hot ticket. Here is a comparison with Dropbox. I know the several of the people at GrabCAD. They know what they're doing.
This post was the easiest to follow in seeing how the concept worked. http://blog.design-point.com/blog/2012/august/how-to-model-a-plastic,-living-hinge-in-solidworks-as-a-single-part.aspx
http://grabcad.com/library/plastic-living-hinge
The hinge's range of motion can be structured under the Configuration Manager.
The program shown in those pics is SolidWorks by Dassault Systems. It's a really convenient and powerful 3D CAD package but it's pretty pricey unless you can get a student version. An alternative is Inventor by Autodesk: http://www.autodesk.com/products/autodesk-inventor-family/overview
I have friends that actually prefer inventor and at the link above you can try a 30 day free trial. It sounds like you are mainly interested in doing some FEA analysis (force/displacement) if components are removed/added to the chassis. Inventor is capable of FEA simulations -> example: https://www.youtube.com/watch?v=Ug2u7sTWrcw
If you know the brand/manufacturer of the frame you can usually download a 3D model of the frame or component that someone has either made or is provided by the manufacturer. I use grabcad (http://grabcad.com/) for this all the time. Can save lot of time and tedious measuring that may not be possible in some cases to achieve all the detail.
If you need any help or more info just let me know!
I found a site where someone had modeled a golf ball in proe. It looks like they did a lot of work to get there, but that should be a good enough starting point for you. I will keep an eye out.
http://grabcad.com/questions/how-to-create-golf-ball-in-pro-e-r5-0
This seems a good place to start, and also the wikipedia page on gears -- bear in mind that the concept of a gear goes much further than a cylinder with teeth, and you'll find that there are some very cool (and wonky) proof-of-concept gear profiles which do in fact work.
Good luck!
You're going to need a 3d modeler, then.
I'm not one, but I know there are plenty of free 3d models out there already for common guns, example: http://grabcad.com/library/colt-1911-a1-model-goverment-pistol
Whether or not that would work, I don't know.
The one thing I'd love to see in a game like this, is realistic guns!
Well...
I study design multimedia at my school as a subject alongside my other ones, high school. And this year, being year 11 the second last year in high school we had to do something for our 'mini-major', sorta like a big project that is worth a lot of marks in the end of year report in other words.
And people get to choose what they want to do for their project. Me, outta the blue chose to fidget around Maya just because it seemed rather interesting judging by myself have previously seen it as a prerequisite in many job applications (DICE for example).
And after browsing the web for a little while I came across this challenge and thought it would be something fun to do. With no experience at all in CAD designing, the past three months has been quite an amazing ride for me. (no experience as in never touched a proper CAD program before, except Google sketch-up)
Talking about the picture, featured is my own variation of Grabby the bot. Which I designed almost from ground up from sketching, then modeling, UV map + photoshop texturing, brief bumpmapping, basic rigging (for the arms haha), messing with rendering, and photoshop post touch-ups. Being a first timer, and with no teachers being able to help me (they haven't used Maya before... only 3DSmax), the internet has been a great place to learn.
So ya that's my story :) Thanks for reading (if you did :D )
And remember! It's never too late to learn!
Oh and the GrabCAD challenge... If you are really interested in browsing some of the designs that went in (which obviously does not include mine as I missed the deadline derp), go to http://grabcad.com/ and at the top click 'challenges', then tab 'selecting winners'. There :)
Have a nice day.
CAKE DAY :D
This should work:
http://grabcad.com/library/professional-track-race-car-for-latin-american-market
I think you might have to create an account to download it, but it's free.
EDIT: That assembly is super complex and probably a bit much if you're just going to put it in the back of your actual design... but try searching grabcad. It's a pretty good site
It really depends on whether or not you decide to pursue research through graduate studies, or whether or not you plan on going straight to industry. However, to get the most out of your competencies, learn C++ and MATLAB for sure! A great site to give yourself challenges to work toward is Project Euler. If you can, do your best to affiliate with AIChE, and possibly attend conferences, look for material about featured short courses, and read publications/attend lectures to really boost what research areas you're passionate about.
If you like CAD, Autodesk gives students free licenses for their academic-based software, and you can start learning AutoCAD (with that appended plant designing software), Inventor, and 3dsMAX for free with some awesome tutorials featured through their website. All you need is a valid student e-mail address. You can also check out GrabCAD, which is the CAD project equivalent of Project Euler.
Competencies will only get you so far though - the best thing as an undergrad is to try to obtain academic-sponsored research positions, apply for REUs, and also apply for internships with a chemical engineering company. It will really help to but those skills to use.
Grabcad is often a great place to look for solid models of whatever you need. If they don't have what you need, you can put up an "ad" for someone to make it for you. I'm already a member so i can just go ahead and make one for you if you'd like.
Not sure about those specific parts but you might check out McMasterCarr - they sometimes have part files for their components. Also, GrabCAD is another great resource for part files.
If its like guru/freelancer/rentacoder is not going to be easy money imo. You are competing with people who have much lower cost of living expenses.
I suppose the major advantage is people can easily browse your work. So they may not ignore someone with 0 reviews, but a good portfolio.
Still a cool site, here is my profile: http://grabcad.com/thmjpr , badass resume btw :)
Here are the ones I use most often:
I find the first two to be sufficient for 90% of my projects. If I’m desperate I go to McMaster-Carr. If I’m really desperate and I have a part number I will try to contact the manufacturer for a CAD model.
Although they tend to have more 3D printing models, A couple places you can look for inspiration, models you can modify or even something you can use, are:
and
I got the solid model from here:
http://grabcad.com/library/hard-hat-fakey
It's been scaled down to slightly less than 2.5" diameter so as to fit inside the available stock. I used MasterCAM X7 to create the toolpaths, and a Haas 3-axis mill to machine it.
The photos are in reverse chronological order:
Polished with a soft-wheel
Finish pass, as it came out of the machine.
Rough pass #2, spiral roughing. I don't have a photo for rough pass #1, which used the radial roughing pattern.
That's all? I'm sure it's quite effective but you need to up your game mate :)
Have a look at K-baffles as used by the AAC Element, one of the quietest .22LR suppressors on the market. Should be a doddle to churn out on your printer.
Grabcad is a great place to look. You can search around with different keywords but here are the results for "Scooter"
http://grabcad.com/library?per_page=20&query=scooter
What exactly are you trying to do? Maybe screenshots of you existing parts could help? Is it in designing it or trying to get the two to go together in an assembly of some sort?
First, follow the instructions in the link below to turn the .stl file into a usable solid model, otherwise it will be graphics only, and be a huge pain to work with.
Then check out Indent as suggested already.
http://grabcad.com/questions/how-do-i-convert-stl-graphics-to-a-solid-model
I agree with everyone else as far as how to approach this prolem from scratch. Grabcad does have a tulip model that you can download here. Have you 3D printed before? Generally you are looking for an STL file to send to the printer, which the link has.
You could try searching for "yourphone CAD model," and if you're lucky you'll find an enthusiast who has modeled their phone, usually available as a free download. GrabCad has quite a few that I've used before. Only problem is that you or your Etsy contact will have to have some kind of modeling program to interpret the file.
If there is too much detail: use Blender too Decimate the amount of polygons.
If it's less then 20k polygons you can open it in almost any CAD software. Just in case you use SolidWorks, make sure you use the proper way to open an STL for editing purposes:
http://grabcad.com/questions/tutorial-how-to-edit-stl-file-imported-into-solidworks
STEP files is the best options for sharing between different CAD programs (because IGS can have some cross-platform compatibility-issues). When you're using 'modeling' programs your best bet is a high-detail .STL or .OBJ format.
Can I ask why you chose to go with an AMD CPU? From all that I've read about CAD, Intel reigns supreme in most categories involving your work.
Some sources for you:

You could try importing 3D models of components like this one by one and seeing how they all look and fit together? Not sure if it would work, but worth a try?
It was really easy in blender 2.49 but they kind of removed a lot of blender habilities.
back then you would make an instance just for the simulation and put a displacement modifier, so if you change the render object, sim objects changes too.
now you can't simulate with modifiers. so you have to have 2 separate objects. use a displacement modifier to test how bigger/smaller the walls have to be. this will vary greatly with the sim resolution.
but you still might have problems rendering, no matter how perfect your contact is, for this reason in blender http://www.stratacafe.com/forum/topic.asp?TOPIC_ID=14007 or this http://grabcad.com/questions/tutorial-render-liquid-in-a-glass-with-keyshot
some renders like vray can handle this in a easier way. not the case with cycles unfortunately. but it is always a troublesome subject
Try GrabCAD, you might have something that is similar to what you're looking for: http://grabcad.com/library?per_page=20&query=mustang
or maybe SkethcUp Warehouse: https://3dwarehouse.sketchup.com/search.html?backendClass=entity&q=89+mustang
You should contact 3D designers that did something similar to this.
and wouldn't it work if I made the piston directley hollow like in this tutorial ? http://grabcad.com/questions/tutorial-how-to-make-engine-part-7 The question I have though is how to make the flat part afterwards ...
I have been using GrabCAD work bench for my university design projects. They have recently put out a solidworks add-in, it is fairly inexpensive, and allows you to share models with people on phones, tablets, and computers, even if they do not have CAD software installed. It has been really great, and the company is extremely helpful if you have questions.
I remember I had a question about revision control and they called me to explain it.
They're not pretty nor complete but, here are the SolidWorks 2011 files I have from this project. The Assembly isn't complete but all the parts are there and it's pretty obvious how it goes together.
http://grabcad.com/library/illusionist-locket
I also know I made a few slight modifications while machining which I can't recall. I'll be happy to answer any further questions and would love to see others attempts if they happen.
Yea, LOTS of people are thinking about this type of problem - call it GitHub for hardware. They're doing more GUI based stuff though: http://GrabCAD.com and http://Sunglass.io are the major ones.
Do you care to elaborate on what you're thinking?
Some people were wondering about those files.
I can tell you that there sites sharing CAD files already, noting new, really
This start up is supposed to be starting a community where you can post up some models as a portfolio and hopefully get noticed. I can't vouch for it personally, but at least it seems to be a place to get a start.
If you start off with the site GrabCad that might help. I haven't done any paid work there, just used it to play around and get feedback, but it might be an easy way to start.
