About this model

A 3 color assembly for an NES 8-Bit Mushroom Keychain. I printed mine in black and red PLA from Dockwell, and white TIANSE PLA. I had great results with 50% infill. Keychain is double sided, so I made the white be the core, sandwiched between the black and red layer. The red portion is scaled just a hair small so it snaps into place with just your fingers. It still required superglue to stick the black and red to the white layer. But the pieces fit snugly enough together. An oddly satisfying build.
