Bed Gauge and Mount

When you initially set your stop switch on the Z axis. They could ask you to set the nozzle, at a certain distance from the Bed. Ender3 v2 is set at 1mm. So I made this handy little aid, you may use only once. But hey! What the heck, you now have it... And a mount to keep it safe on your Printer. Brill Eh?
