Not sure if this works as expected as I just printed it out and mounted it on my Ender-3 (o;
The 608 bearing should help being less abrasive than the original filament guide.
The mounting is the same as the original filament guide so you can easily switch back in case it doesn't work for you (or for me ;o).
You need to print:
- 1 * Filament Guide
- 1 * Bearing Roller
2 * Bearing Spacers
- 1 * End_Clip.STL from the original design
For mounting you need:
- 1 * 608 bearing
- 1 * M4 x 16 screw
One side has a slightly bigger hole, this is where the M4 screw goes in and it should cut a thread into the other sides hole.
