<h4>If you could do me a favor?</h4><p>I like filament. If random internet people like and download my model, Josef Průša will send me a truckload of Prusament Orange PETG. That's right, he's going to personally drive it from Europe across the Atlantic to my house in the United States. Trust me, I have an agreement.</p><p>Don't worry, you can just download it and sent the models straight to your trash. Hell, just throw your entire machine in the trash, I really don't care, as Iong as that truck gets here.</p><h4>And now for something completely different.</h4><p>Remix of <a href="https://www.thingiverse.com/thing:5387968">https://www.thingiverse.com/thing:5387968</a></p><p>I have the Creality metal wheels on my Ender 3 v2 printer and as such could not use the original model. &nbsp;I thought it was a fantastic idea.</p><p>If your printer software tells you how to turn your bed wheel nuts to level your print bed, then this model may help.</p><p>I use Klipper and the <i>SCREWS_TILT_CALCULATE</i> macro to help with bed leveling. &nbsp;Small turns, like “CW 0:15” (quarter turn clockwise) are easy enough, but sometimes a helper may want to turn the bed screw when you're not looking and the correction is “CCW 1:25” (one full turn and 25 minutes counter-clockwise). &nbsp;It's hard to keep track of where the starting point is.</p><p>So what this hack does is make a pointy end on one small sector of the wheel. &nbsp;So you can feel that nub as you move it, and you don't have to go back and forth with the software to get it right.</p><h4>Instructions / Warnings:</h4><p>The source is commented. &nbsp;I will put a brief “how-to” at the head of the file for OpenSCAD also. &nbsp;But in short, change variables, Render, then Export as STL/3MF. &nbsp;Done.</p><p>Each of these clips should print pretty fast, probably around 10 minutes apiece or less, depending. &nbsp;I did them in PETG but I think PLA should work fine.</p><p>I did 0.24 layer height and 5% infill with PETG. &nbsp;The key is flexibilty so you can get it on and off. &nbsp;You can change the thickness of the clip with the variables if you want to.</p><p>I am a big variable fan. &nbsp;You can change many things at the top of the file. &nbsp;There are a few local variables in the modules. &nbsp;Hack it to pieces, I won't stop you.</p><p>You can try to raise the text labels but I had better luck embedding them. &nbsp;The raised text came out a bit bumpy. &nbsp;Set <i>engrave_top</i> or <i>engrave_vert</i> to true in the call at the bottom of the code if you want to check it out.</p><p>If your wheel is slightly different than mine, change the paramenters in the .scad source file.&nbsp;</p><p>Bust a Nut Clipper or four. &nbsp;You'll feel a sense of relief and satisfaction.</p><p>Or bust eight nuts, two on each side of each wheel, two different colors for even easier turnings.</p><p>Just don't bust them all at once. &nbsp;You have been warned.</p><h4>Future Plans:</h4><ul><li>I will add the clip for the standard black plastic wheel, I just have to find it in my boxes of bags of printer parts.</li><li>Better jokes.</li></ul><h4>Change Log:</h4><ul><li><strong>June 3, 2022</strong><ul><li>Added “None” to vertical label options. Now it is easier to change the characters of the vertical label. &nbsp;The search() fuction cleaned up the list lookups.</li><li>The clip was made a tad wider for better nut clipping action.</li><li>Label engraving heights and clip dimensions were slightly tweaked for a better fit</li><li>Hilarious paragraphs were added to the model description.</li><li><strong>Nut washer added</strong> – nut clipper was not moving freely, causing the printer some discomfort. Either throw an M4 washer or two between the wheel nut and the screw or wash your nuts with the ones in the print</li></ul></li><li><strong>June 15, 2022</strong><ul><li>Changed OpenSCAD source for easier use of OpenSCAD Customizer (Window -&gt; Customizer from OpenSCAD Menu). See <a href="https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Customizer">OpenSCAD Documentation</a></li></ul></li></ul>
