Ender 3 Sensorless Y Endstop

thingiverse

So, I see that you're converting your Ender 3 to a sensorless endstop setup? You can swap out the switch for this more robust part. It fits perfectly into the original mount on the Y axis. # Perfect results from the start. If you use Cura, set your nozzle to 0.4mm, In Quality set Wall Line Width to 0.5mm, wall thickness to a multiple of 0.5mm (like 2.0mm), and Wall Line Count equal to thickness divided by 0.5mm (four wall lines for 2.0mm thickness). If you use Slic3r, Print Settings > Advanced > External Perimeters = 0.5mm.
