Spiral earrings

prusaprinters

<p>This is my collection of 3D printable earrings.</p> <p>The entire project has started as research into capabilities of my Prusa MK3S. I wanted to know how precise it is, how big overhangs I can print and so on. So I generated one type of earrings, "twist1", and then, well, just continued playing with them :) They can all be printed on a FDM machine, but may look even better if printed on a SLA printer.</p> <p>All earrings are fully parametric. They are created from an OpenSCAD script "spirals.scad" (attached). In addition, you will also need my set of OpenSCAD libraries, available for download at <a href="https://github.com/gabr42/3D/tree/master/lib">https://github.com/gabr42/3D/tree/master/lib</a>.</p> <p>Entire project is available on GitHub at <a href="https://github.com/gabr42/3D/tree/master/earrings">https://github.com/gabr42/3D/tree/master/earrings</a>.</p> <p>This collection contains seven earring models: twist1, twist1_lp, twisty4, twisty5, twisty6, tree1, and tree2.</p> <p>To generate one mode, open spirals.scad script in OpenSCAD, uncomment appropriate "make = ..." declaration near the beginning of the script, press F5 for a preview, F6 to render the result, and F7 to create an .STL file. Or you can use make_earrings.bat script (<a href="https://github.com/gabr42/3D/blob/master/earrings/make_earrings.bat">https://github.com/gabr42/3D/blob/master/earrings/make_earrings.bat</a>) to regenerate all files.</p> <p>Each earring is generated only in one version (left/right). Select it in PrusaSlicer, right-click and choose "Mirror, Allong X axis" to create a second earring of a pair.</p> <p>Don't forget that you can later adjust earring dimensions in the slicer and further customize them in that way.</p> <p>Some earrings are composed of multiple parts. You can create parts separately in OpenSCAD (for example, define 'make = "tree2a"' instead of 'make = "tree2"') or with the make_earrings script.</p> <p>Multi-material printing can waste lots of material on the wipe tower so I have included small script "wipe_object_generator.scad" which generates a square or round vase with specified dimensions. You can set it as a "wipe object" and the use it as a storage for earrings - or for anything else.</p> <p>Three 3mf files are attached:</p> <ol> <li><p>earrings-vase: Contains earrings that can be printed in "vase" mode.</p> </li> <li><p>earrings-spiral: Contains all earrings.</p> </li> <li><p>earrings-mm: Contains multi-part earrings, each split in parts.</p> </li> </ol> <p>To finish an earring, you have two options;</p> <ol> <li><p>Drill through the earring near the top and pull through a simple wire hanger (you can get it at a local hobby art store).</p> </li> <li><p>Super-glue a cap on the top (hobby art store will sell you those, too; or get them in bulk at a friendly chinese supplier).</p> </li> </ol> <p>See the images for more ideas.</p> <h3>Print instructions</h3><p>Most of the earrings require brim because the contact surface is quite small.</p> <p>Some earrings may print better with supports. As a suggestion, earrings-spiral.3mf contains hand-made support structure for "twisty5" earrings (put together entirely in PrusaSlicer).</p> <p>If you are printing in a single material, I'm suggesting printing earrings one by one. This makes for a better print and reduces stringing. Alternatively, space them far apart on the plate and use "Output options, Complete individual objects".</p> <p>Use shiny or translucent filaments, they create the most effective result.</p>
