Spool‑Hole Filament End‑Lock SNAP Clip

A tiny spool‑hole end‑lock that keeps your filament tip from slipping back inside the spool.
Just snap it onto the outside of the spool hole, push the filament end in, and it stays put.
Fast to print, easy to use, and works on any standard 1.75mm filament.

Note: This model can be resized with the STEP file available.
