Ender 3 Pro Bed Leveling Lock/Discretizer

thingiverse

Not entirely satisfied with existing designs, I created a fixture that secures bed leveling screws in place while allowing them to be rotated through 8 distinct steps. The knob clicks over the steps in a manner reminiscent of moving a rotary encoder on an LCD display. The part is not symmetrical; the STL file fits front-left and back-right. To print the other sides, mirror the design in your slicer for front-right and rear-left. Inspiration came from various sources: https://www.thingiverse.com/thing:3530329 https://www.thingiverse.com/thing:3611855 https://www.thingiverse.com/thing:3537995 https://www.thingiverse.com/thing:4154042 When using auto-bed-leveling, this fixture is a necessity; without it, the resolution may be too low. Testing was conducted on an Ender 3 Pro and it likely works with similar models like the Ender 3. However, the Ender 5 has a different nut that is much flatter and its compatibility remains unknown.
