I designed this version of a Vortex Fidget Toy to have something other than the taper shaped ones.

Printed with 0.4 - 0.2 layer, I used support on buildplate for part 1.

Scaling up will also enlarge clearance. (base model has clearance of 0.2mm / 0.1mm per side).

Usable as a presse paper or to brag about the accuracy of your printer.

In case the clearance is too tight I have added a Sphere part 1 with +0.2mm extra clearance.
