Warning: Assembly and hardware required!!!
I personally used M3-.5 x 6 for all three screws, without magnets because I had them from previous projects. I also applied a small amount of glue to every block, most of the corners have a snug fit but I glued anyways. You'll need 3 screws per build. On my last build I decided to clean/drill the holes with a 5/64 bit and it helped the tapping/threading process. The original creator has a good building video so I will let him explain the build. Print profile has concentric pattern because I believe it looks better than monochromatic.
Print plate 1 and 2, but the build list is below, make sure to watch the assembly video before starting the project so you know what you're getting into.
See the assembly video for step-by-step instructions.
Latch.stl x2 Many of these parts snap together, but the puzzle will feel most solid if any piece that doesn't need to move is also glued in place.
