<p>Fidget Spinner</p><p>I designed this spinner to recycle used roller blade bearings and entertain the neighbor kids.&nbsp; Put the best spinning bearing in the center location of this spinner.</p><p>Bearings size:</p><p>20 mm outside diameter</p><p>8 mm inside diameter</p><p>7 mm wide.</p><p>Print in your school or favorite team colors.</p><p>The buttons in the center bearing allow you to hold the spinner down on a flat surface and give it a really energetic spin or hold it between your thumb and forefinger to feel the gyroscopic forces.</p><p>I used PETG filament but PLA should work fine.&nbsp; All parts press together without the need for glue.&nbsp; I printed with a 0.40 mm nozzle at 0.20 mm layer height with 100 percent rectangular infill and 5 perimeters on&nbsp; a Prusa MK3S+ machine.&nbsp; All parts can be printed without supports.&nbsp; &nbsp;Push the 4 bearings into one of the housing halves.&nbsp;Press the second housing half onto the first half firmly.&nbsp; Press the button with the large hollow axel onto the center bearing and press the button with the small axel onto the first button’s hollow axel.&nbsp; Press all the parts together firmly and start spinning.</p><p>&nbsp;</p><p>Part&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Print time&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Grams</p><p>Frame with holes &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 63 min&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.7</p><p>Frame with pins&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 65 min&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12</p><p>Button with hole&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 8 min&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.3</p><p>Button with pin&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 7 min&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.2</p>
