Broomstick Reel Holder for Ultimaker

Holder for broomstick (diameter 22 mm) for filament reels.
Most reel holders for small diameters I tried did not work well. But we don't need to print everything, an old broomstick might be smarter than 3D print.

I do not support companies forcing lawsuits based on trivial patents against other 3D printer companies.
