Filament Clip

This clip is designed specifically for Prusament spools with the hexagonal pattern and 1,75mm filaments to ensure a good grip.
Using it the first time, you might need to use more force to push the filament through the hole.
But after that the filament is easy to insert while still holding the firm filament enough so it cannot fall out unwantedly.
Before inserting, cut the end of the filament.

Easy to print. No brim, no supports.
