Pi Puzzle

A neat puzzle I designed two years ago while bored in class, I made the model back then but never bothered to upload it until now. It started as a pencil drawing, was refined with sharpie, scanned into the computer, turned into a vector, then extruded into a 3d model in Fusion360. You don't have to use different colors, but I find it makes solving it easier as no same color pieces touch.

(P.S. If anybody knows if there are any similar tile designs to the I used please tell me, I just kinda made it up as I went)

(P.P.S. Sorry about the large amount of files, if I figure out how to combine multiple parts into one file I'll update it but until then sorry for the time waste)
