Prusa I3 Y-idler Tensioner

thingiverse

Fairly dissatisfied with numerous Y-Idler tensioners, a determined hobbyist opted to take matters into their own hands and craft one from scratch. Ideally suited for printing on its side, additional scaffolding supports the bearing retainer perfectly. Employing two high-quality 625 bearings ensures stability, while M3 screws provide precise support. To accommodate smooth sliding of M3 nuts, these will require a slight modification to the Y-motor mount design.
