Wanted to have a small, compact sensor mount, as I am using the filament guide wheel: https://www.printables.com/model/831717-ender-3-v3-ke-filament-guide-wheel/comments/1698841
Tried several designs and positions, ultimately ended up with a little mount, added some nice chamfers to it.
Later I saw similar designs, though without a threaded hole for the sensor mount - might be a small advantage compared to the other designs. My Ender 3 V3 KE printed it well and assembly was flawless.
Used following settings, and printed several parts already, seems stable and strong enough - though if PLA is good enough for longterm usage, only time will tell:
