All my testing to date on the improved actuators for SMMB have used 3d printed parts from Shapeways. Both to have a faster iteration time, and to reduce costs, I’ve optimized all the parts to be printed on my Prusa MK3s.
Here’s all of the individual parts:
Them assembled into a leg with the other necessary hardware:
And some jumping on that leg (caveat, this video is from the previous endurance testing post):
A full set of leg parts can be printed in PETG in about 12 hours and uses a little less than 90 grams of plastic.
