A couple days ago I was struck by a whim, I wondered if I could make a passable figure of Heavy and Bomb from Knuckles Chaotix using nothing but Tinkercad. It actually only took me about 2 hours to make the models, and then I printed the parts out for assembly. The only parts I didn't make myself were Heavy's hands, which I modded from a 4 inch Knuckles figure. Heavy has swivel movement at the shoulders, neck, wrists, and ankles, while Bomb is just a single piece with no moving parts.
