I made a 3x3 Square-1! (Waterfall Cube)

The Waterfall Cube is a 3x3 equivalent of a Square-1. The Square-1 is two Windmill 2x2x3 puzzles superimposed, while the Waterfall Cube is two Windmill 3x3s superimposed. It is made by extending a base mini 3x3 with 3D-printed parts, with two separate outer layers. The puzzle shape-shifts quite a lot, and is fairly difficult to solve, requiring cuboid and Square-1 algorithms.
