Here is a model of a cheapo servo that I made a while ago. I actually used this in a computer model of a (flimsy) robot arm I had made. I had most of a simulation hacked togther in Blender before i abandoned the project. I might pick it up again now that I can print a proper arm!I made this back when I was exclusivly using Imperial units, and before I had my calipers. The parts all seemed close to some fraction of an inch though?Print mockup.Use to test fit parts?(I'm not sure why you would print this, but the model could be useful for other things)
