Ender 3 locking bed knob modification

Last crawled date: 5 years, 6 months ago
I found several knob modifications that were something like this, then I also found some spring cups for maintaining the position of the springs better.
This modification is a sort of combination of the 2 ideas, giving you locking knobs that also keep the springs positioned well. All pieces slip pretty easily into place over the stock knobs that come with the latest Ender 3.
The knobs make a satisfying clicking sound as you adjust them, with teeth positioned every 12 degrees, so you could figure out exactly how much each click raises or lowers the bed if you wanted to.
** Note: this doesn't fit on the corner where the bed cable guide mounts, so I'll be making a modified version of that to add to this in the future.
***Note update: I've added a mashup of the lockingPlate with a bed wire "strain relief" bent 90 degrees downward from the standard configuration.
****EXTRA NOTE: I haven't printed or tested the new bed wire "strain relief" yet, but I don't expect any wild complications from it. I will update again when I verify functionality.
