Aurora A3 Y-Axis Tension Adjustment Idler Mount (whew!)
thingiverse
Untested, Caveat Emptor! Not sure this will be strong enough, but give it a try if you wish. Uses 4x M3 bolts and nuts to provide tension on the idler bolt giving you 5.6mm of play. I basically stretched the stock Y-Axis idler mount and added holes for the bolts and nuts. Print Settings: Printer: JG Aurora A3 Prusa I3 Rafts: No Supports: Yes Resolution: .2mm Infill: Lots Notes: Probably needs supports for the nut holes. I recommend 1.2mm thick walls/top/bottom and lots of infill for added strength. You're welcome!
