Make your own custom impossible passthrough hourglass shape. You can customize the dimensions, number of sides, the spiral shape and twist degrees, the number and size of the blades, and more!

3mf files require supports for printing outside shape and any support scarring needs to be shaved off for smooth passthrough.

Printability of custom models may vary. Less twist rotations (examples max out at 360) and larger space between blades may improve printability.
