Prints well with my i3mk3s, but be prepared to do a few attempts at the gears to get a perfect fit. I will post the BOM later, but it's included as the names of parts in the .stp. Prices of the parts will vary a lot, denpending where you buy. The places I was buying from are all in Polnad so won't probably be relevant for most of You.

I'm pretty sure you'll need to modify the way it's mounted for you won design. I just left some 'suggestions' for hole placements, feel free to delete these. I'm uploading a .stp and an .f3d.

I've developed this reducer to be used in my Atlas robot arm.

Thank you for posting the files. This project is awesome! I look forward to learning how this drive works. Do you plan to post the CAD files for the 6 axis robotic arm in the future?

Sorry, but i won't do that, that was my first project this size, it's not polished enough, and would be extrely hard for anyone to replicate, i don't want people investing this much time into something that contains so many mistakes. Mistakes that i just don't have time to go back and repair. I chose this peace of it as a fragment i can document well enough, that is pretty polished, and that i hope to maintain in a way that would allow others to benefit from.

I totally understand and thank you for explaining. I was just so excited when I came across your project as it had features I've seen on larger robotic arms. For example, the many gear reductions and the way the timing belts twist and turn in the wrist joint.
