It should resize well as I used basic trigonmetry to help maintain a good shape.</p><h3>Print Settings</h3><p><strong>Printer Brand: </strong>Creality Ender 3 v2</p><p><strong>Rafts: </strong>No</p><p><strong>Supports: </strong>Doesn't Matter</p><p><strong>Resolution: </strong>0.20</p><p><strong>Infill: </strong>15%</p><p><strong>Filament:</strong> Dollar General Cost Cutter Extreme PETG Screaming Green</p><p><strong>Notes:</strong></p><p>I only had bed supports, but they may not be necessary. My latest print time was 11 minutes.</p><h3>How I Designed This</h3><p>At this point, December 1, 2021, I have not yet even fired up my laser engraver. I printed the @lewiswalsh print and it had a smaller diameter than I needed, so I hacked this together since the construction is fairly simple.</p><p>I have a few Christmas gifts planned for later this month and I will adjust variables and post new versions if I find a better way.</p><h3>Custom Section</h3><p><strong>Making Changes to this Print</strong></p><p>Some of you might be intimidated by OpenSCAD. If so, this is for you.</p><p>If you have to make a change to the model, I think that's the best way. The .scad file is just a text file and I (think) the variable names are clear enough so you can make your own changes. It is a parametric model and should adjust itself accordingly.</p><p>Basically, you do these steps:</p><p>Download OpenSCAD. It runs on many platforms.</p><p>Open the .scad file with OpenSCAD. You can also try the Visual Studio Code plugin -- that's what I normally use. You still need to install OpenSCAD to visualize your changes.</p><p>Make changes.</p><p>In OpenSCAD, hit the F6 key or Design -&gt; Render. It wiil take a moment or two depending on your CPU, etc.</p><p>Save as STL, 3MF, whatever.</p><p>Slice and dice.</p><p>Do a cartwheel (required).</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Other</p>
