Ender-3 Filament Sensor, Top Mount, SUSH Compatible

thingiverse

Thjs is a REMIX of joshual33's modified Ender 3 Filament Sensor Bracket, top mounted for direct drive and configured for use with superhans' SUSH top mount spool bracket (linked below), allowing the spool holder legs to be pushed easily into place at the perfect distance apart for a 1kg spool. The mod printed in under an hour and effectively completed my Ender 3 Direct Drive conversion! SUSH - Slide-On Ultimate Spool Holder https://www.thingiverse.com/thing:3401216 Here is the micro-switch that I used: https://www.amazon.com/gp/product/B07X142VGC/ This mod also holds the filament in place when the Z-axis raises to park, keeping it from unraveling on the spool (!)...and it provides super smooth feeding of the filament as the extruder pulls it through. Update: Depending on how it's positioned, this bracket may cause a small filament bend inside the Teflon tube when left idle for a while, which can affect first layer adhesion. I've found that the best way to deal with it is to just pull a little bit of filament through the tube before launching the job. This gets the bend out and relieves any tension in the filament path that may be present. In my experience, this works every time.
