Kawai Tsugite Puzzle Box

thingiverse

After printing the Kawai Tsugite customizable puzzle (2821085), I thought it would make an interesting puzzle box. The cube is hollow inside. Photo 2 shows how to open it. Print 4 copies of each object (Box1 and Box2) and assemble after cleaning up the joint surfaces. The objects are the original 30 mm, but they can be scaled to 200% for a larger inside volume and better assembly tolerances. No supports required.
