Y-Axis GT2 Idler

thingiverse

I wanted smoother operation of the Y-Axis belt, so something more robust than the standard design was needed. To achieve this, I redesigned the idler using a GT2 Idler bearing that provides greater stability. A small offset was incorporated to prevent the bearing from binding against the idler sidewalls when tightened in place. An M5 nut and bolt (24 mm) were used to secure the idler mount and GT2 together, with the nut and bolt head recessed a few mm for a solid fit.
