Thicker Spool Lip 1.75mm Filament Clip
This is for filament spools that has a thicker lip. My BotFeeder filament spool lip is about 6.3mm thick. The iGo3D one is far too thin for it, so I remixed it to a slightly larger size. Also, on the original, the clip for the filament was a tiny bit too tight, I slightly enlarged it in this, so you can print this as is, and the 1.75mm filament should fit easily.
