Cube Helical Pass-through Toy

I am publishing a series of similar fidget toys in other shapes but with the same helical geometry, so they all can mesh together. These cube helical pieces simply thread into themselves. You may thread them through the center bore onto a standard wood pencil or the included optional skewer to assist aligning for assembly, but really just another way to fidget. Spinning them on a shaft can have unexpected and entertaining results. Not all pieces spin equally freely. Detailed cleanup makes a big difference. I find the easiest printing orientation for these cubes is flat on one face, with floating edges well support. This orientation tends to result in some fusing and friction between separate pieces, so spinning is hindered. For the best spinning results, print the cube oriented tipped up on a corner with sufficient supports to hole the model upright and support floating sections. Some cleanup will still be required. The clearance between pieces is very close. High temperatures can caus
