Filament Spool Collar – Anti-Roll Swatch for Shelf Storage
Designed by Jakub Skála

This simple yet effective collar keeps your filament spools in place and prevents them from rolling off your shelf. Designed to snap around the spool and act as a flat swatch or marker, it’s especially useful for vertically or loosely stored spools.

Ideal for makerspaces, workshops, or home setups where spools are stored sideways or on open shelves.

✅ Easy to print
✅ No supports needed
✅ Compatible with most standard spool sizes
