filament spool roller

cults3d

Fully 3d printable spool roller. You can add a 5mm diameter and 30 to 60mm long wood screw, to reinforce the axle. Its optional. It fits any carrier that has 21 to 30 mm hole in it. I tested it on ender 3, ender 3 v2 and cr 10. Assembly: watch assembly gif. Place the housing vertically on the table, insert the axle then insert 8 rollers and secure them by screwing on the flange. Repeat on other side. Screw on the attachment nut. Use a coin or large screw driver for counter force.
