Filament clip for Inland (MicroCenter) filament spools

This is a filament clip specially designed for Inland (sold in MicroCenters) 1.75 mm filament (1 kg) spools.

UPDATE: If the spool is very full, the filament tends to stuck into the clip during printing (if you don't remove it). The r2 now has a small chamfer which (hopefully) will prevent that.
