This is a quick and easy clip for your filament spools, so you don't lose the tip and, more importantly, you don't have to try to fish the tip through those little holes in the spool (which often makes a kink in the filament that then needs trimmed off, wasting some filament every time).
Riffing off the design by @KefmaDE_1573339, I've just made a more compact version.
No supports, no nothing. super simple print.
I print basically everything I design (or remix), so you can go to the “Makes” tab to see an actual printed version of this.
The author remixed this model.
I made it shorter and thinner so it takes up less space on the spool's edge and prints faster
