An OpenSCAD version of the idler for the PG35L ExtruderThis is an OpenSCAD version of the V4 idler for the PG35L Extruder (PG35L Micro Extruder V4 - For J-Head). The original one is not available as an OpenSCAD file.It is not an exact replica but appears to be close to enough to work for me.It is designed for a 624 bearing and a M4 nut and bolt.It's tweakable for other bearing and nut/bolt sizes, but you may need to play with the distances a bit besides changes the bearing dimensions. If someone finds optimum factors for 625 and 623 bearing I'm happy to update this one.
