Nikon F-mount lens to Fujifilm X-mount body

This adapter is based on two different pre-exisiting models:

https://www.thingiverse.com/thing:2583009 - Sony E-Mount body to Nikon F-Mount Lens adapter - by Harh (for the Nikon lenses side)

https://www.printables.com/model/438188-fuji-x-mount-template - Fuji X Mount Template - by cewo (for the Fuji X-mount body side)

I couldn't find an already made design so I tried to make one myself.

I followed the info here for flange focal distance and while it's not perfect, it's close enough for me. The lens I tried this with (Nikkor 50mm f/1.8) does focus to infinite, but the minimum focusing distance is about 60cm instead of 45cm, so I'm sure this could definitely be improved.

On the Fuji side, the adapter locks in with the camera body, while the Nikkor lens just stays in place through friction (so I don't know if I would trust it with heavier and longer lenses without some kind of support)
