Hi Folks, On the Ender 3 V2, the normal switch mount has the switch too far towards the back of the printer. Under normal circumstances, that doesn't effect anything, but if you have an automatic bed level sensor added to it, then the two will interfere with each other. I now have my switch at 230mm on the Y axis by making a new custom switch holder for the Ender 3 V2 that extends it further forward to allow for printers with ABL as well. You can find it here: https://www.thingiverse.com/thing:4663605 (Look in the files for the Ender 3 V2 specific one.) Bill

Here's one I tried putting together for the Ender 3 V2 Y-axis. Adapted from Bill's tinkercad switch mount collection. Screws into the lower left-hand slot of the Y-axis extrusion. Hole for the bolt and T-nut are offset as is the slot guide to allow the switch to be mounted closer to the end of the Y-axis rail. The offset also allows the bolt and T-nut to be accessed even with the switch board mounted in place and is low enough to allow clearance for the wheels.
I've printed and installed one. Seems to work though I've yet to try it out operationally. This one should be able to be placed beyond the 220.0 mm y-axis spot that interferes with the bed leveler. I've not yet been able to test it outside of the normal 0-220 mm range using the marlin controls on my ender 3 v2. Have yet to try using gcode to drive it into the switch. Hopefully the firmware allows this and doesn't clip the bed motion. I'm not very experienced yet with this stuff.
Probably not the best model geometry after my hacking away at things but at least I'm having fun while learning!
