Lack Table Filament Sensor

thingiverse

I needed a sensor that would work seamlessly with my direct drive assemblage, but the Ender 3's frame was positioned too closely to the bottom of the Ikea lack table for any conventional mounting arrangements. A runout sensor installation required some creative problem-solving due to space constraints. Mounting one directly on the extruder wasn't feasible because it would have resulted in a considerable loss of build height, a compromise I was determined to avoid. This design has proven its effectiveness for me so far; I've created both straight and tilted versions. JoyMonkey's design perfectly complemented the switches I had at my disposal. Please bear with the rough modifications, as this is my first attempt at modifying any device. The mods were created using TinkerCAD.
