Thumbs Up For 3D Printing!
A silly robot which interlocks so you can puzzle a bunch together and cover your entire wall, if you so please.
Parametrized for your enjoyment.
I tried to upload a POV-Ray file to be automatically rendered, but it doesn't seem to work?
(Or, if I did something really stupid in the design process. Tweak parameters, print, puzzle).
Could also be cut on a laser.
Edit: I have now printed a few of these, and have found out they don't interlock properly in the current state, and are too thin. Redesign coming up.
