Filament Spool Insert (2.25")
thingiverse
I'm no designer by any stretch, but I threw these little inserts together so my filament would sit better on my spool holder. I'm using it with a 2.2kg Hatchbox filament spool, but it should work on any with a 2.25" opening in the spool and a 1" shaft. It takes a bit of force to get them in the spool so they stay in there well. Print Settings Printer: M3D Rafts: No Supports: No Resolution: Low Infill: Low
