Idler Pulley - All plastic, no bearings

thingiverse

This is an idler pulley assembly for the X and Y-Axis. It is inferior to a steel ball bearing assembly but works fine so far. It is always good to have one as emergency replacement. These pulleys may squeak like hell. :D Note: Friction will be much stronger and the rotation may be eccentric leading to lower print quality. Use only for emergency until your replacement bearings arrive. Version 1: Outdated version with a rod diameter of 5mm. Can break during operation but still works in broken state. Y-axis only. Version 2: New version with higher rod diameter of 6mm. Slimmer but robust bracket. Made for X and Y axis. Thumbscrew is included. Print Settings Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.3 mm Nozzle, 0.2 mm Layers Notes: Additional brim is included for rod for better adhesion. The rod may overheat during printing (not operation) and loose its precise diameter. This must be compensated by sanding afterwards, or by printing two widely separated rods at the same time. Post-Printing You maybe have to sand the rod after printing. You can use silicone spray for lubrication. Oil (WD40) somehow increases friction.
