Spiral Hourglass (Fidget Toy)

Elegant and satisfying fidget toy.
Compatible with [Spiral Balls](https://cults3d.com/en/3d-model/game/spiral-balls-fidget-toy-deadcat1337) and [Parametric Spiral Cone](https://cults3d.com/en/3d-model/game/another-spiral-cone-parametric-f3d) with default parameters.

Outer part (SpiralHourglass.stl) may be challenging to print, so I added the SpiralHourglassSupported.stl file. It has 3 layers of bridges between columns. Remove those bridges with cutters or knife before use.
