I have the Creality Run Out sensor on my Ender 3 V2.

This comes with a new bracket for the X-Gantry that is wider than the standard one so the sensor has somewhere to sit.
This renders most other chain mounts useless.
So I created this to mount on top of the filament run out sensor using the 4x bolt holes. You can use the original countersunk bolts or cap head bolts if you have a stock of them.
Hole for the light on the sensor, there's an optional diffuser. I printed this with Clear PLA at 100% infill. Works a treat.
Takes about 56 minutes to on an E3V2 using stock Cura settings.
If using new bolts, you will need - 4x M3x19mm
Printed at 0.2mm with 15% infill and is plenty strong enough.
