Hey Damian. Nice project! One question: Where to buy the inner pins?

Do you have a BOM please?

Hey Damian. Great job on this. I am mining it for some ideas on a project with similar needs (massive gear reduction).

I know that you said you wouldn't post the CAD files because they aren't polished enough but I would urge you to reconsider. Work like that doesn't need to be perfect to be extremely valuable for the community. Just be clear about their state and see what people do with them.

Personally I would love to dive into some of the concepts you are using. I don't have any intention of building the full robot arm at this time but seeing how someone like you creates your designs always inspires new ideas.

The hacking and creating community isn't about perfection. It is about sharing your creative work out in the world to see what happens to it.

Don't let perfection win, it is a brutal enemy that never lets you free once it catches you.

do you have any plans to start designing and selling these on a case by case basis? Definitely interested for it’s camera applications. Not sure it could carry my red dragon though could it?

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.
