Ender 3 Pro Bed Leveling Lock/Discretizer

Not really happy with the other designs out there, I designed a fixture that keeps the bed leveling screws in place while allowing the screws to be rotated in 8 discrete steps. The knob can "click" over the steps in a way that resembles moving the rotary encoder on your lcd.

The part is NOT symmetrical. The stl fits front-left and back-right. Mirror in slicer for front-right and rear-left.

Thanks to the inspiration:

I use it with auto-bed-leveling. Without it the resolution is likely too low.

I tested with my Ender 3 Pro. Will probably work with Ender 3.
Ender 5 has a different nut that is much flatter.
