Fixing Knob for Extruder mounted filament guide

thingiverse

I designed a filament guide specifically for the Ender 3 / Pro after completing a 12-hour print, I noticed that it had vibrated loose from the bracket. This innovative Knob enables you to secure the Guide firmly to the bracket without any risk of coming loose. Ideal for printing on an Ender 3 Pro printer, set your printing quality to extremely high for optimal results. To effectively tap the thread: - Drill a precise 4mm hole in the guide above the slot designed for the bracket. - Use a sturdy 4mm bolt to tap the hole securely. - Place a 4mm nut firmly in a vice grip. - Position a few small washers on the shaft of the knob, leaving a small space at the start of the thread (the washers will help keep the thread straight). - Gradually remove one washer each time it reaches the nut until the nut meets the knob head.
