About this 3D model

I saw the video by Devin on his MakeAnything Youtube channel. I figured modeling this would be a good excuse to get more familiar with Fusion360. So I followed some Devins methods to build this 4x4 Puzzle Cube. The method of push/pulling faces is much faster than fully defined sketch methods in Solidwork. So for quick non-critical dimension parts like this Fusion360 is much faster. I have included the STL's, the original Fusion360 archive file, a Step version, and a version imported back to Solidworks. Hope you enjoy, it is actually more difficult than you might think with only 10 pieces to the puzzle. Note: if you run into problems solving it, I added a PDF visual key to help. But don't use it until you have given it a go. Attribution: Thanks to Devin for the inspiration: https://www.youtube.com/watch?v=3xdhxQkK3Xw&t=19s
