What? Another filament clip?
Apparently everyone who gets into the filament clip game has to try them all to ultimately end up designing their own. This is what I've done, and probably what you will too, and so here is my contribution to our endless quest towards the ultimate filament clip.
This one integrates a lot of excellent ideas from previous clip designers, as well as a few new ones. It clips to the filament itself instead of the spool, so you can stack your spools. It has nice chamfered edges so that even if your prints suffer from elephant foot the clip retains good dimensional accuracy and won't require any post processing.
Both clip "channels" are located on the same side, making it easier to insert filament, and there's a small tab to make it easier to handle.
The download includes both a 1.75mm and 2.85mm versions.
