Ender 3 V2 locking bed knob modification

EDIT (28.2.2021): Before print of this, take a look at TheBoJaN's Ultimate Ender3 Bed Leveling Knob. IMHO it is far more superior (or at least it also solves unwanted moves of bed during "clicks").

Although it is remix, it is redrawed from scratch (mainly because I was unable to import STL to FreeCAD without geometry/mesh errors)

I like the original idea, but real "thing" has some flaws:

• Spring should be against bed plate, to avoid unsprung gap.
• Gap for plate is too wide.
• Benjiis Bed Wire Strain Relief is not usable for Ender3 V2, because V2 has PSU there. I redrawed new one, using FourDogs "bed wire strain relief" as etalon (same issue with mesh errors - I had to completely redraw it from scratch, as a visual copy).
• FourDogs Bed Wire Strain relief has to be lower, to avoid nipping the wires.

All of it is fixed in this remix.

Knob adaptor, "lockingKnob", is benjii original (no modification was needed) as well as FourDogs "Wire_Strain_Relief_Bracket_Lid".

What you need to print:

• 4x lockingKnob
• 3x MyLockingPlate
• 1x MyLoweredStrainBracket
• 1x Wire_Strain_Relief_Bracket_Lid (optional)

-Generally, it is best to print these parts with the teeth facing upwards.

-However, for the part that slides over the plate, you may want to rotate it so the teeth face sideways to minimize support.
