Ender 3 V2 locking bed knob modification

<strong>EDIT (28.2.2021): Before print of this, take a look at TheBoJaN's <a href="https://www.thingiverse.com/thing:4743835">Ultimate Ender3 Bed Leveling Knob</a>. IMHO it is far more superior (or at least it also solves unwanted moves of bed during "clicks").</strong> 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. * <a href="https://www.thingiverse.com/benjii">Benjii</a>s Bed Wire Strain Relief is not usable for Ender3 V2, because V2 has PSU there. I redrawed new one, using <a href="https://www.thingiverse.com/FourDogs">FourDogs</a> "<a href="https://www.thingiverse.com/thing:2958812">bed wire strain relief</a>" 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 <a href="https://www.thingiverse.com/benjii">benjii</a> original (no modification was needed) as well as <a href="https://www.thingiverse.com/FourDogs">FourDogs</a> "Wire_Strain_Relief_Bracket_Lid". What you need to print: * 4x lockingKnob * 3x MyLockingPlate * 1x MyLoweredStrainBracket * 1x Wire_Strain_Relief_Bracket_Lid (optional)
