What would an interlocking puzzle look like for 2d beings? This is the end result of my exploration of that question. The goal is to pack the 4 pieces into the box so that no part is sticking out. It's easy to put the pieces together when you are allowed a 3rd dimension, but the box restricts you to moves only available to our 2d friends. 

The box is printed in two parts that can be snapped together, so that no supports are needed to print. I've found that the box stays together well without glue, but you could add some drops of gorilla glue if you don't want anyone cheating by taking the box apart.

There are two stl files: one for the box and one for the 4 pieces. You'll need to print each of those files. I printed them in different colors but that is purely for looks.

I'm not sure how difficult the puzzle is but I do find it fun to play with. To disassemble, you can just keep rotating the puzzle until all the pieces fall out, hence the name Pinwheel Packing Puzzle!

If you get stuck or have some suggestions, just drop a comment and I'll be happy to respond.
