Works way better than the original version!

I've been trying to figure out how to mount my run-out sensor since I switched over to a direct-drive extruder and belted z-axis on my Ender 3 V2. This fit the bill perfectly! I did end up filing down the extrusion mounts and using a T-Nut so I didn't have to completely disassemble the Z-Axis but so far it's working great!
@ChrisOyler Good to hear it's working! I didn't like how the rigid mount for sensor still was causing some friction, so I've made Mount V2. Check it out some time if you plan to change later :D (edited)
