Small Hands Spinner (625Z)

prusaprinters

<p>I designed this spinner for my 6 year old son since the standard configuration of 4 608ZZ bearings is too big for his hands. The outer bearings are now 625Z bearings with a diameter of 16mm instead of 22mm.</p> <p>To be clear, the center is still a 608 bearing as I've found that the smaller bearings don't spin nearly as well in this size of object.</p> <p>I recommend using the knobs designed by CPME listed here:<br/> <a href="https://www.thingiverse.com/thing:1979370">https://www.thingiverse.com/thing:1979370</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Wanhao</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Wanhao Duplicator i3 V2</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.3</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>10%</p></div></p> <p><strong>Notes:</strong></p> <p>These pop off at about 15 minutes apiece with my current settings, so you can hammer out 4 in an hour, easy.</p> <h3> Post-Printing</h3> <p>Hammers work, but I've been using channel lock pliers to squeeze the bearings in along the edge of a picnic table: one side of the pliers under the tabletop, one over the bearing.</p> <h3> How I Designed This</h3> <p>I used Fusion 360. Simple circular array with a little bit of filleting.</p> </p></p></p> Category: Mechanical Toys
