Belt idler guide

thingiverse

Here is a custom designed idler guide for 13mm bearing that is perfectly suited to the majority of three dimensional printers. One issue I've noticed is that the belt tends to wear down at the edge of the tensioner/idler, which isn't exactly ideal and could potentially result in the belt breaking at some point. By incorporating this handy little guide, you can significantly improve your machine's overall performance by reducing friction caused by belt grinding on the edge, ultimately yielding a smoother and lighter motion. Unfortunately, during initial assembly I discovered that the bearing holder was rough to the touch, suggesting that some surface scraping may have taken place along the edge. In all likelihood this could produce numerous small plastic particles. To ensure optimal use of your three dimensional printer and maintain a well running machine consider these guidelines for creating the perfect idler guide. Assembly instructions: My print employed these settings successfully - ABS Layer Height 0.1mm Bed temperature: 110c Extruder Temperature: 230 This idler guide will definitely work as expected, allowing your printer to perform at its peak capacity.
