Quad Fidget Spinner

prusaprinters

<p>I tried to make the model with a durable, stable and, above all, soft edge. First test models had sharp edges and were uncomfortable to use.</p><p><strong>Required part:</strong> 608ZZ bearings or any 608 bearing<br><strong>Bearing dimensions:</strong> 8 * 22 * 7mm<br><strong>Dimensions of the spinner:</strong> I designed the bearing location to be 21.8 mm. This will hold the bearings properly, but will not break them.<br><strong>Dimensions of the knob: </strong>I designed the knob pin to 8.25 mm.&nbsp;</p><p><strong>Bearing preparation</strong></p><p>The bearings I bought needed preparation because they didn’t really spin from the grease.</p><ol><li>Check that the selected bearing rotates, is not clogged, broken bearing balls, etc.</li><li>Soak in alcohol such as isopropyl. for a few hours.</li><li>Remove from alcohol, clean or blow out with a high pressure compressor.</li><li>Pour a little instrument oil on it, turn it a few times and wipe it off.</li></ol><p><strong>Assembly</strong></p><ol><li>Of course, print out the modell. = D</li><li>I used a press to insert the bearings, but it can also be used with a rubber hammer, a smooth, strong flat table, or a vise.</li></ol><p><strong>Comment</strong></p><ul><li>I made it from PLA, but there was a pla that broke several times with the same settings as the others. It happened with one of the 6 types of pla.</li><li>I tested the model with a high pressure compressor and several random drops, and it worked properly.</li><li>With this type of bearing, I was able to achieve 45-80 seconds of rotation, depending on wear.</li><li>The Prusa Galaxy Black and Azure Blue look really good together.</li></ul><p><strong>Print Settings</strong></p><ul><li><strong>Material:</strong>&nbsp;Several type Pla</li><li><strong>Nozzle:</strong>&nbsp;0.4mm</li><li><strong>Layerheight:</strong>&nbsp;0.2mm</li><li><strong>Supports:</strong>&nbsp; Spinner: None / Knob: Build plate only</li><li><strong>Infill type:</strong> Grid</li><li><strong>Infill:</strong> 30%</li></ul><p><strong>Color Changer - Z layer height&nbsp;</strong></p><ol><li><strong>Black:&nbsp;</strong> &nbsp; &nbsp; &nbsp;0 .00- 0.80</li><li><strong>Blue:</strong> &nbsp; &nbsp; &nbsp; 0.80 - 1.40</li><li><strong>Black:&nbsp;</strong> &nbsp; &nbsp; &nbsp;1.40 - 5.80</li><li><strong>Blue:&nbsp;</strong> &nbsp; &nbsp; &nbsp;5.80 - 6.40</li><li><strong>Black: &nbsp;&nbsp;</strong> &nbsp; &nbsp;6.40 - 7.00</li></ol>
