Stewart Platform

thingiverse

A robot Stewart platform, that uses 5 gram hobby servos. Hopefully every part (except servos) will be 3d printed. I'm using the small universal joint I designed. So far I've printed the hinges and base plate. I'm still working on the servo holder/linear actuator. I've uploaded the extra files I used. They're what I happened to print at that point in time, so the numbers of each part aren't exact. I'll sort this out later. It's a bit wobbly at the moment. I think I'll move to a ball and socket joint for the top plate as it'll be a lot simpler, I can make the tolerances tighter and they'll be zero chance of acetone accidently sticking the parts together. Video of it moving here https://www.youtube.com/watch?v=hRBGwyz43d8 Instructions I printed with ABS. I used straight 3mm abs filament as the axles. I used acetone to glue the axles to the hub (small cube with holes). Hub and axle need to be within the clamp part before gluing starts. Glue one axle first and then drill though the holes to make space for the second axle. Be careful when gluing otherwise hub and clamp may get stuck together.
