OK, this is a remix of a a puzzle box I found here on Thingiverse - but I can't find the original any more! So all credit to that mysterious maker for the maze!
For Easter, I designed an egg to enclose the puzzle box, because let's face it, kids have it way to easy on Easter! I tested this at .3, and it works just fine, although I printed mine at .2.
Both models should be printed open side down, with supports. With a pair of pliers and a little wiggling, the supports on all 3 that I made popped right out of the gap between the egg and the cylinder.
