This mod is UNTESTED and is a modification of the Prusa Core One's CAD files. I am not responsible for any damages done to your printer, please use this mod at your OWN RISK.
This mod will help eliminate VFA (Vertical Fine Artifacts) that are caused by the belt teeth rubbing on the smooth idlers located on the XY Joints, this is a common cause for VFA in all printers. While I cannot guarantee that it will remove all VFA, it should at least get rid of any VFA caused by the belts rubbing, the 12mm idlers used by Prusa are way out of Gates spec for minimum size, so this mod should help both in accuracy and reducing VFA.
You will need:
- 2x 25mm x 5mm Dowel Pins (may need sanding)
DO NOT substitute the 20T idlers for POWGE or other 8.5mm tall idlers, they will not fit and WILL NOT match Gates profile
The files are ready to print and I have included .F3D and .STEP for those who wish to modify, happy printing and enjoy! This mod is designed to use 5mm x 25mm pins! Thank you to Prusa for providing the CAD files. Please print in ABS or ASA, avoid Nylons and PETG.
