Extruder Gear Brush Mount
thingiverse
Im sure Im not alone with this issue, but my dual gear extruder tends to get filament build up on the gears, leading to slipping and bad prints. To solve this I made a simple wire brush mount to continuously clear the extruder gears of debris. Use a M4x6 bolt to secure the brush in place. Original extruder mounting screw is not long enough, a longer screw is required.
