<p><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></p> <p>Although it is remix, it is redrawed from scratch (mainly because I was unable to import STL to FreeCAD without geometry/mesh errors)</p> <p>I like the original idea, but real "thing" has some flaws:</p> <ul> <li>Spring should be against bed plate, to avoid unsprung gap.</li> <li>Gap for plate is too wide.</li> <li><a href="/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="/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).</li> <li>FourDogs Bed Wire Strain relief has to be lower, to avoid nipping the wires.</li> </ul> <p>All of it is fixed in this remix.</p> <p>Knob adaptor, "lockingKnob", is <a href="/benjii">benjii</a> original (no modification was needed) as well as <a href="/FourDogs">FourDogs</a> "Wire_Strain_Relief_Bracket_Lid".</p> <p>What you need to print:</p> <ul> <li>4x lockingKnob</li> <li>3x MyLockingPlate</li> <li>1x MyLoweredStrainBracket</li> <li>1x Wire_Strain_Relief_Bracket_Lid (optional)</li> </ul> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3 Pro</p></div> <p><strong>Rafts:</strong></p> <p>Yes</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> PM PLA Yellowgreen</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Printing orientation:<br/> -Generally, it is best to print these parts with the teeth facing upwards. <p>-However, for the part that slides over the plate, you may want to rotate it so the teeth face sideways to minimize support.</p> </p></div></p></p></p> Category: 3D Printer Accessories
