Really neat robot. Any chance for a "no support structure needed" revision?
V3 will be no support needed. If I tell you I'll post it by the end of July maybe I actually will.
Hard to say, the body is the only part that needs support, and it only needs support because I couldn't figure out a way to rotate it so it wouldn't. If you were to remove the two thigh pins (and replace it with a hole) and make the pins a separate part, you may be able to print it without support.
Wow! It looks amazing! Thank you for making this design workable. I'm still plugging away at it, but it's slow work. Any lessons learned about the design now that you've printed it?
It had just a few clearance issues, the hand and thigh wouldn't fold all the way at first so I had to trim some parts.
The majority of the new pins are too delicate because they are being printed skyward, so I had to greatly reduce their "snapping" ability. Ideally, the pins should be separate pieces printed on their side and possibly about half their current diameter. I've included an image of one of my failed
attempts. Perhaps this could be some more upgrades for v3 :)

Scales really well. I printed one at 75% but I'm confident it'll print at 50%.
I'll be uploading a deritive that puts them all on one plate and has printed supports for the body. Assembly was tricky, I got everything on the wrong side the first time, but the leg's shape in the body was key to figuring it out.
