Lotmaxx SC-10 Filament strain relief guide with bearings
thingiverse
Filament Guide for a Lotmaxx CS-10. I tried multiple filament guide designs, but none of them resolved the issue. The grinding noise persisted at the runout sensor where the filament entered. So, I drew inspiration from Ponestar619's Filament Strain Relief Guide (https://www.thingiverse.com/thing:4268991). I modified the overall dimensions by incorporating a U-groove pulley with two 608 bearings. This setup worked flawlessly! When installing the bearings in the pulley, ensure approximately 1mm of space on each side of the pulley. Secure the bearings using an M5x8mm button head screw and printed washer. Preferably use an M5 tap for threading. Drill a hole through the pulley with a 5mm drill bit and secure it with a longer M5 screw and locknut. Note: I used a support blocker to change the infill density to 100% for the bearing shaft throughout.
