Filament Guide Roller for Creality CR10, CR10S, Ender 3, Ender 3 Pro, others

I've tried several of the Filament Guides and Guide Roller designs, and none of them seemed to fit right or work well for me. I didn't want to buy a bearing, so I made this one using a simple nail as the axle shaft. This design is truly SIMPLE AND WORKS! The concave roller centers the filament before it enters the filament feeder, allowing the filament to flow smoothly. This improvement has greatly enhanced the quality of my 3D prints! I threw away the "eyelet" type guide and replaced it with this roller version. I also tried another roller type guide, but it was huge and the roller kept falling out. I printed in PLA, fine detail, with 15% infill. I used a 3mm aluminum nail for the roller shaft, but any 3mm bolt or shaft material will work. Happy Printing!
