Prism Z belt springy idler
thingiverse
This Z-axis belt idler is designed for Prism Reprap printers by Buback. It serves two main purposes - allowing use of longer closed belts like original Mendel sets and reducing wobbling caused by printed Z pulleys. Extra benefits include better belt engagement on driving and driven pulleys, and easy tension adjustment. To use, modify size in OpenSCAD for your belt length (100-110cm), print, add a 4mm internal diameter bearing with washers, mount the motor support, idler, and adjust tension as needed. Consult Thingiverse's downside view picture for assembly guidance and fine-tune wall thickness/infill settings to avoid excessive vertical flexing.
