Hexagon 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 hexagon 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 best printing orientation is with the end fins up. If you orient the ends down on the plate you may need some supports or a good brim to keep them from falling during printing. The clearance between pieces is very close. High temperatures can cause fusing. I advise low temp material (PLA) and placing on the bed near the open door to maximize cooling. I find on the smaller models you can also increase the cooling time for each layer by printing 2 or more clones simultane
