100% Printable Spinning Nail Polish Carousel

prusaprinters

<p>My daughter asked for a spinning nail polish organizer and this is what we came up with together.</p> <p>Everything is printable, including the bearing wheels and tires (if you can print TPU). I also included a TPU pad for underneath to save surfaces from being scratched.</p> <p>The bearings are a highly modified version of the 606zz_mk2.stl bearing from here:</p> <p><a href="https://www.thingiverse.com/thing:2746804">https://www.thingiverse.com/thing:2746804</a></p> <p>Besides having the square cutout and rims, the entire bearing mechanism is tighter, which keeps the rods from falling out all the time.</p> <p>The bolt is modified from bolt_25x8_socket.stl here:</p> <p><a href="https://www.thingiverse.com/thing:2746804">https://www.thingiverse.com/thing:2746804</a></p> <p>Beyond that it's all home grown.</p> <p>Assembly should be pretty self evident, but I left some notes in the print instructions in a few places just in case.</p> <h3>Print instructions</h3><h3>Print Settings</h3> <p>Lots of printer notes. See each section below.</p> <h5>Bearing and Hub</h5> <p>I used carbon fiber PLA for the bearings, and happened to print the hub using the same material. Bearings are tricky in general, and these are no different, so I would start here so you know if you can actually get a spinning version or if you want to skip the spinning parts. It took me quite a bit of experimentation to find print settings that worked - like a dozen tries or more - but I finally settled on the parameters listed below. After gently working the bearing around with some WD-40 they spin really well.</p> <ul> <li>Rafts : No </li> <li>Supports : No </li> <li>Nozzle : 0.5mm </li> <li>Resolution : 0.12 </li> <li>Line Width : 0.4 </li> <li>Infill : 100% </li> <li>Filament : carbon fiber PLA </li> </ul> <h5>Top, Bottom, Base, and Bolt</h5> <p>The top, bottom, base, and bolt were all printed with standard PLA. I'm sure you know how to do that.</p> <p>I glued the top and bottom together with Krazy Glue and it worked out well. Keep in mind that the nubs (bottom) and holes (top) are for alignment while gluing and not meant to actually keep the parts together. You may need to clean up the holes in the top a bit depending on your printing tolerances... but if those are off good luck with the bearings ;)</p> <ul> <li>Rafts : No </li> <li>Supports : base.stl only </li> <li>Resolution : 0.12 </li> <li>Infill : 50% </li> <li>Filament : PLA </li> </ul> <h5>Pad and Tires</h5> <p>The scuff pad and tires were printed from TPU.</p> <p>I sanded the tires a bit so they weren't so slippery and gripped the surfaces better. The pad I stuck to the bottom using Elmer's spray adhesive.</p> <ul> <li>Rafts : No </li> <li>Supports : No </li> <li>Nozzle : 0.4mm </li> <li>Resolution : 0.2 </li> <li>Line Width : 0.4 </li> <li>Infill : 100% </li> <li>Filament : NinjaTek Cheetah TPU</li> </ul>
