Great job! What kind of CAD software? Maybe I didn't pay attention but why does the first image have two motors coupled to it?

Hello. I’m having some difficulty installing the gearbox into the arms. It’s a very tight fit. Is that intentional? Afraid I’ll break it if I have to disassemble.

It is kind of intentional, it’s caused by tight clearances and layer lines, once you slide it in Out a couple times it’s not so bad.

Really cool idea . Now I'm thinking to add 2 motors on one joint to rule the 2 joint with proper transmission. You light my bulbs. Thanks for sharing

I'm not sure I understand what your saying? Are you saying you want to put a transmission on this somewhere?
