Slide Puzzle 3x3

This is a design inspired by Maker's Muse's recent challenge to make a print-in-place slide puzzle! [Link here.](https://youtu.be/7KJ-RB6S3vY) My first design has 45 degree angles, and a horizontal clearance of 0.5 mm.

There is no pattern on the top of the puzzle, but a sticker can fix that! I'll design another one soon with a topographic map on top.

Included .f3d file in case you want to play around with it. The design is just okay, but it works.
