Cardboard Spool Rim - Reduce Friction From Cardboard Spools

Cardboard Spool Rim - Reduce Friction From Cardboard Spools

thingiverse

A simple rim that clips around the outside of a 200mm cardboard spool. Designed to fit around KiwiFil spools. Print 2 of these, one for each side. I found that this substantially reduces friction for spools to roll smoothly, resulting in more consistent extrusion. I would reccomend printing this in something more heat resistant than PLA to prevent the rims deforming when drying the filament spool under heat
