40mm Drain Hair Filter/Catcher

I designed this to catch the hair that constantly gets stuck down our plug-hole. With this design, the hair gets caught in the slots and ties itself around the walls.
Fits a standard 40mm plug hole.

Can scale reasonably well up to 65mm, but then it stops being circular.

Print it either way up. Suits a .4mm nozzle due to the wall and surface thicknesses.
