6 Piece Puzzle Cube

I designed this model in Tinkercad as a school project a year and a half ago and never did anything with it, so I printed it, loved it and published it! This cube is 52mm³. It is layed out on the plate so that when complete, the shiny (sparkly) side is facing out. (If textured PEI is used) Please leave a comment and a review! If there is any way I can make it better, let me know! I would love some input. IMPORTANT NOTE: (Tolerances between pieces may vary depending on printer settings. I realize two of the pieces look weird and hollow in the file but they will print the same as all of the others.) If you enjoyed this model, consider boosting me! It would be much appreciated.
