Idler Pulley - All plastic, no bearings

thingiverse

This is a standard idler pulley assembly designed for X and Y-Axis usage, albeit slightly inferior compared to steel ball bearing assemblies. It works satisfactorily up until now. Possessing one as an emergency replacement option is always beneficial. Users are advised to be aware that these pulleys may produce loud squeaking sounds during operation. Due to increased friction levels, rotational issues may occur, potentially leading to suboptimal print quality outcomes. It's essential to use this pulley only in case of emergencies until you acquire new bearings as replacements. **Current Assembly Variations:** **Version 1:** This outdated assembly version features a rod diameter of 5mm and might fail during operational sequences; nonetheless, it still manages to function properly despite its flawed state. The assembly is limited for Y-axis usage only. **Version 2:** In comparison, the latest model boasts a heightened rod diameter of 6mm, a slimmer yet robust bracket, making it compatible with both X and Y axes. A thumbscrew comes included within this setup. **Printing Recommendations:** - Rafts settings remain open-ended; users are encouraged to use their discretion when choosing appropriate configurations. - Supports requirements similarly can be set as desired without strict specifications needed from users. - Opt for a Resolution of 0.3 mm with the Nozzle, and adjust the Layer setting to 0.2mm. *Add additional brim to ensure better rod adhesion. *Be cautious: over-printing temperatures might lead to an oversized precise diameter that then necessitates sanding or multiple printing attempts in separate sequences, thus achieving the required outcome for rod accuracy.* **Post-Print Tasks:** - Sand down any remaining ridges following completion. -A thin silicone lubricant coat offers suitable protection while avoiding oil-related increase in friction, hence making it more suitable than using WD40.
