Tetris 4x4x4 puzzle cube

Inspired by a 3x3x3 origami puzzle cube. I wanted to make one with the actual Tetris pieces, which requires at least a 4x4x4 and 16 pieces. The solution I chose uses 4x T, 4x S, 4x L, 2x I, and 2x O pieces. You may find other solutions! My first original 3D design, I'm very proud of how it turned out. Printed in 4 colors of ProtoParadigm PLA in the photo.
