Ender 3 / Pro Filament Roller Guide

thingiverse

I've modified the original STL file to incorporate 2 F695-2Z-EZO rollers that guide filament without noise. The original one sometimes makes cries when the extruder retracts as the filament touches the edges of the hole. List of materials needed: 2 x F695-2Z-EZO / 1 M5x20 CHC Screw This design complicates printing by adding supports, but it works fine. I also added a small hole for the cables retainer to use a collar. Note: This is designed for the common spool holder on top of the printer. If you're using a lateral spool holder mod, this accessory may not be useful. 1. The original STL file was modified to incorporate 2 F695-2Z-EZO rollers that guide filament smoothly. 2. These rollers eliminate noise caused by friction between the filament and the edges of the hole when the extruder retracts. 3. A list of required materials includes 2 x F695-2Z-EZO rollers and 1 M5x20 CHC Screw. 4. This design adds some complexity to printing due to additional supports, but it functions well. 5. I also added a small hole for the cables retainer, allowing the use of a collar. Note: This accessory is designed for the standard spool holder located on top of the printer. If you're using a lateral spool holder modification, this accessory may not be compatible.
