thingiverse
Introducing a new Y-idler with tightener functionality that allows the addition of belt guides along with or without bearings. The idler can be easily inserted using a clip and doesn't require removal of the entire threaded shaft. Required components include a 623 bearing, an M3 screw for fixing the bearing, an M4 screw with hex head, and an M4 nut. The belt guide is parametric and specifically adjusted for the Y-idler (623). Upgrades available include a stronger version and a wharf option, both equipped with more robust hooks to prevent breakage. STL files are ready for printing.
