    Adding speed control to the motor. It had one speed and that speed was super fast, so now there's a knob. #3dprinting

    Same automata, now on a motor instead of the hand crank. It goes at a super fast speed. The crank is more dignified. This is more fun.

  3. A hand slowly cranks a 3D-printed automata: a magenta Octorok (the Zelda octopus) bobs up and down on a grey printed frame.Video

    My first automata. It's an old Zelda print, an Octorok, that I finally painted, riding a cam I made by animating the motion in Blender and printing the curve. Crank the handle and the little guy dances.
