Geeetech A10 A20 A30 Roller Filament Guide v3

thingiverse

This is a filament guide designed to ensure smooth running of filament into the extruder on the A10 printer, with potential compatibility for other Geeetech printers as well. To implement this solution, you will require a standard skateboard/fidget spinner type bearing. Consider scaling up the M8 nut by 102.5% or substituting it with a steel nut and bolt if available to prevent excessive tightness.
