Are you frustrated with your filament clip? Do the clips come off when you slide them in and out of your storage bin. Do the different hole patterns in the spool cause problems with the clip? They did for me, so I created yet another clip. This clip slides in between the rolled filament and the side of the spool and does not protrude outside the spool. All your rolls can happily sit side by side without fear of them coming off during spool handling. Only takes minutes to print a full plate of them.
.STL, .STEP and Fusion 360 design file are included. This clip is for 1.75mm dia filament, but could easily be modified for 3mm.
