Filament Guide for CR10-S in enclosure

thingiverse

I've successfully built an enclosure for my CR10-S, but encountered a problem with underextrusion due to excessive friction. The filament is currently supported by a stand on top of the enclosure, causing it to enter straight down through the roof and into the filament runout sensor. Upon reaching the sensor, it must make a sharp 90° turn to reach the extruder, resulting in significant friction that leads to underextrusion. It's highly recommended to create a spool mount that holds the spool with centered bearings like mine (see pictures) to minimize friction. To solve this issue, I designed a guide with a bearing that can be directly attached to the filament runout sensor. This allows the filament to be gently guided into the extruder, as it moves up and down with the sensor. As a result, the guide functions perfectly at any height level. The necessary components for assembly are: - The two printed parts, print the support as shown in the picture on the mirror bed. - An M8x35mm bolt + matching washer + nut - Two M4x15mm bolts + matching washers + nuts - A 4mm drill to create holes that keep the support connected to the sensor, as depicted in the pictures - One bearing (from a skateboard) with dimensions D22xd8 x7mm wide
