That is tricky. My plan is to print another hose adapter, mount it to a long piece of sheet material, and stick it in the window only when printing.
I wonder if a combination of hepa and charcoal filters could make it ok to vent inside? Something like Carbon Air Filter!

That’s the carbon filter I have. It comes with the straps and the dust cover
This is my first grow, but from others experience, i expect it to last at least a year, so probably a good 2 or 3 grows.

That's the filter I have on my 2x2 tent now and I cannot smell a thing 1 month into my grow.
Not Vivosun. That's the only brand of carbon filter I've seen several people complain about (here and on r/autoflowers), consistently mentioning them stopping working after a couple months.
I use this one by G-HYDRO. While it may not be the best, it seems as good as the Phresh filter I was using, but significantly less expensive.
If you use a humidifier, use distilled/RO water in it -- minerals from the tap water in my humidifier clogged the Phresh filter, which was a pretty expensive lesson. :/
Here's an inexpensive but effective 4" carbon filter and a cheap but adequate fan. I wouldn't depend on that fan for a tent (it feels really cheap), but it's all right for running with a freestanding carbon filter to scrub the air now and then.
All right, you can fit in your tent. :) I'm taller than mine. In any case, depending on that is probably risky. I probably wouldn't grow in an apartment, because harvesting would make me a nervous wreck, but that's me.
