Post-Printing

Sanding and lubrication can be done for longer spin times, but the G3 works about as well as a new, sealed bearing spinner straight off the printer.

How I Designed This

Software used.

            <div><p>Onshape for the basic shape, and I used TinkerCAD to merge the shape with my existing bearing design.</p></div>                <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/89/8b/6a/da/d7/Screen_Shot_2017-04-18_at_7.12.11_PM.png"></p>            <p class="detail-caption"><strong>The image above is a screenshot of the G3 that was designed for a 608ZZ bearing and 6 pennies for each side. Will be added as soon as I refine it.</strong></p>
