Filament Clip - Square Edged

Yet another filament clip. Rather than twist or contort the loose end of your filament to hold in-place by hole locations on the reel, this clip provides a simple way to clip and un-clip the loose filament during storage.

The clip fits onto the edge of the spool reel. The clip has been optimised for a spool reel with a 3.7mm square edge. The reel also has a 1mm indent step 8mm from the edge, as implemented on the Aurarum filament brand. Other filament brands may fit well, too (there are so many brands!).

In most cases, you can leave the clip in position on the reel whilst printing. It's tiny, at only 10mm high. The filament facing side is angled to avoid the spooling filament and not get snagged. The filament lightly snaps into place, but holds well in storage.

I hope you can find this print useful, too.

Print instructions

I've printed the clip in both PLA and PETG. The clip seems to flex better in PETG. My print is made in PETG 1.75mm Aurarum white filament, with 0.2mm layer height and 25% infill on a PRUSA I3 MK3S printer.
