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.&nbsp;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.&nbsp;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.&nbsp;<h3>Attribution:</h3>Thanks to Devin for the inspiration: <a target="_blank" href="https://www.youtube.com/watch?v=3xdhxQkK3Xw&t=19s" rel="nofollow noopener">https://www.youtube.com/watch?v=3xdhxQkK3Xw&t=19s</a>

This mechanical design model showcases a large variety of parts essential to mechanical gearbox design. Not only does this model look great assembled on a desk or shelf, assembling and disassembling it can teach you a lot about the use of bearings, gears, seals, and other elements of mechanical design.&nbsp;I assembled by model using two 40mm x 52mm x 7mm ball bearings and three M6x10 screws, but if you don't have these on hand, don't worry! Included in my print profiles and raw model files are demonstration bearings matching these dimensions. While your shaft won't spin quite as smoothly as with real bearings, they will certainly suffice to assemble the model and allow you to play with it. The screws aren't necessarily essential either. They are easy to find in any hardware store, though, and definitely contribute to the sturdy look and feel of the model.As you can see, I made the shaft printable in two parts. These can be glued together permanently after printing.&nbsp;Happy assembling!
