Triangle Labs Filament Runout Sensor Mount For Ender 3

prusaprinters

<p>I designed this mounting bracket to hold a Triangle Labs filament runout sensor on the top extrusion of an Ender 3.</p><p>I previously had a BTT smart filament sensor on this printer but decided to move it to my Voron V2 and replace it with a simple sensor from Triangle Labs. The spool mounting hasn't changed from my <a href="https://www.printables.com/model/163997-bigtreetech-smart-filament-sensor-mounting-kit-for">previous sensor</a> so you can look there for the spool mounting bracket.<br>&nbsp;</p><p><br><strong>Hardware Required</strong></p><ul><li>M3 x 12mm bolt (top of filament sensor)</li><li>M3 x 20mm bolt (bottom of filament sensor)</li><li>2x M3 washers (bolts through filament sensor)</li><li>M3 x 10mm bolt (top of bracket)</li><li>2x M3 hammerhead nuts (top of bracket and bottom of sensor)</li><li>M3 x 4mm x5mm heatset insert (top of filament sensor)</li></ul><p>Alternate version uses an M3 nut and a longer bolt (16-20mm) on the top in place of the heatset insert.</p><p>&nbsp;</p><p><strong>Printing Instructions</strong></p><p>Print part flat on bed, no supports needed.&nbsp;</p><p>3 walls 20% infill should be fine.</p><p>&nbsp;</p><p><strong>Installation</strong></p><ol><li>Inset the heatset insert with a soldering iron</li><li>Attach the filament sensor to the bracket</li><li>Place the hammerhead nut on the rear bolt and slide onto top extrusion</li><li>Slide a hammerhead nut under the bracket and insert top bracket bolt</li><li>Tighten the bolts into hammerhead nuts</li><li>Wire up the runout sensor and configure in marlin/klipper following documentation for the sensor/mainboard/firmware</li></ol>
