Filament sensor mount for Ender 3 S1 (requires M3 thread insert)

thingiverse

For use on Ender3 S1 where a custom enclosure or modified feeder system is employed. I liked the original from which this remix stems, but the change I've made allows for the use of a gripped M3 thread insert, as shown in the photos. I had such an insert already, but such can readily be acquired from various online retailers. My insert is 4mm deep and a fraction over 5mm diameter, thus the hole is 5mm so that it grips well. I inserted the M3 thread insert by holding it in place with tweezers and pressing down with a soldering iron, thus making it hot and melting it into the hole.
