Matter3D Filament Clip

This is my take on a filament clip that clips in to the tear-shaped holes in the spools used by Matter3D for their filaments. I've included a standard version and a tight version as I've found there is significant variation from spool to spool - the standard fits best in most cases but if it fits too loose the tight option can be used.I printed these in ABS as the idea is that you can clip them on when you first open a spool and leave it on for the life of that spool, including drying. It would likely work with other filaments but I'd recommend printing just one first and scaling the model as needed since other filaments shrink less than ABS.
