A google search seemed to take me to more than one tool to do it:
I would think most CAD programs can do it too. Try FreeCAD and see if it can.
Hey! i downloaded the okami model from here: http://tf3dm.com/3d-model/amaterasu-okami-98001.html
converted it to stl (3d printable) here: http://www.greentoken.de/onlineconv/
you can download the converted 3d printable model here: http://www.filedropper.com/okami
The scale might be off so if they dont check the scale before printing there, let me know, and i can try to get it right.
if you have windows 10, you can open it natively on your computer to make sure it looks right.
No idea how legit it is but you could try an online converter, like this one...

I could do it but due to network security restrictions I can't upload anything at work.
If you have the obj files, just use this (http://www.greentoken.de/onlineconv/) to convert them from obj to stl.
Before I start, I'm going to assume that you know that this needs to be scaled to your body and have the proper measurements. If you don't, reply and I can help.
After that, you'll need to use a couple different free softwares to get it ready: Autodesk Meshmixer and Autodesk netFabb Basic. Once you have the stl, import it to Meshmixer, change the scale using Edit, Transform, Scale.
After that, Select, Ctrl+A, adjust the Offset Distance until you don’t see the black and white stripes on the inside (in my case about -3.5). Adjust Accuracy and Resolution to 100% Check the box for “Connected,” this makes the offset part of the model rather than a separate one.
For cutting the helmet down to fit your printer, I prefer not to use dovetail cuts or mechanically join them, as I finish them afterwards with paint and putty. If you’d like to use something like that, check out MatterHacker's article here. Import your new file from Meshmixer, then using one slider at a time, adjust the plane that will cut the model into sections. I choose to split it in spots that would be easy to sand or glue together. Press execute cut, select “Cut all parts," press Cut. The model is now sectioned in two. Repeat until the model is split into enough pieces to fit on your printer. If you don’t want to slice through all parts within the window, select one part (it will turn green) and change “Cut all Parts” to “Cut only Selected Parts." Right click on each part you have cut out, select Export, name and save the part as STL. Import to slicing software of your choice, mine being MatterControl.
Let me know if there's anything you need elaborating on!
I actually just googled it. Found this site and it worked pretty well. Also, I've been using Makerbots which actually support printing from .obj files, so I realized halfway through that I don't even have to convert.
I used to use that site because I wanted to make animations, so I've always converted the STL file using sites like http://www.greentoken.de/onlineconv/ for STL to DAE etc. (though I wouldn't recommend that as it strips UV data; there's been far better tools created by people to actually extract all the information).
Might be possible to correctly format it to a working STL using an online converter like that one, or look at a STL file that you know works and compare it to the generated STL file from that site. Just open them in Notepad++ and see if there's any formatting changes you can make. Might be as simple as that.
Actually there is a easier solution I use this website http://www.greentoken.de/onlineconv/?step=3&outfmt=obj it converts your file to a obj. or any of the formats listed.
You spent 3 days and not once did you actually try to Google this?!?
Within 1 minute I found more than one online resources that would convert files from one format into another, including OBJ to STL.
As Moranic said to convert builds to obj, then use this fantastic but terribly unappreciated website to convert the files. I haven't done it but I imagine it would work, I've used the website for previous things.
turned out the only thing i need to do is make sure i didnt have any large flat faces and just divided them up a bit and that took care of my problem, if thats not the case for you, you can try a "file converter" ... one like this... http://www.greentoken.de/onlineconv/ just take the raw blender file and swap it with this and it should work
what file type do you need? stl? Make can export .dae (collada) files, then you can just use an online converter.
Also, there are plugins for sketchup you can easily get to export STL files directly.
if its some other filetype, im sure there are equivalent methods.
I tried all three options available for viewing the print slicing. Nothing worked with the OBJ file, but it didn't spam me with errors when I sliced it.
I did find a converter online: http://www.greentoken.de/onlineconv/ I converted one of my builds, a castle, to .STL I loaded it to Repetier-Host, which took a lot longer than .OBJ for some reason. I can view layer by layer now, but I have another question. The slice render is different from the initial setup/scaling area. Does this mean the object being printed is too difficult/impossible? http://imgur.com/FEjLKqe.jpg
