<h3>2U (3U) Raspberry Pi mount for 19" rack</h3><p>A rack mount for up to 12 Raspberry Pis.&nbsp;<br>2U if the Raspberry Pis are powered via the GPIO pins.<br>3U if powered via USB (Due to the cables sticking out).</p><p>Heavily inspired from <a href="https://www.thingiverse.com/thing:4078710">this design</a>, but completely remodeled. In my design, you can pull out a Raspberry Pi without having to unplug the power cord.</p><p>The PoE HAT should fit like in the original, but since I don't own one, I can't verify that.</p><p>The honeycomb pattern requires a very clean print bed!</p><h4>Needed Hardware:</h4><ul><li><strong>3 M6 threaded rods</strong>. Cut to <i>at least</i> 452mm length (Should fit exactly through all frames, the ears and two nuts. Depending on the available space, the threaded rods can also be slightly longer.)</li><li><strong>10 M6 nuts </strong>(6 for the threaded rods, 4 to mount the ears to the rack)</li><li><strong>4 M6x20 screws </strong>(to mount the ears to the rack)</li><li><strong>48 M2.5x16 screws </strong>(4 per Pi)</li><li><strong>48 M2.5 nuts </strong>(4 per Pi)</li></ul><h4>Provided files (respectively)</h4><ul><li>stl</li><li>step</li><li>gcode</li></ul><h4>Updates</h4><ul><li><strong>2022-04-24 </strong>initial upload</li></ul><h4>Print Settings</h4><p><strong>Rafts: </strong>no</p><p><strong>Supports: </strong>Depends on the printer.
