Cover for Raspberry Pi 40-pin GPIO Connector - UART pins exposed - GND and Pin1 indicators

prusaprinters

<p>Based on <a href="https://www.thingiverse.com/thing:1874648">https://www.thingiverse.com/thing:1874648</a> but fully rebuilt (because of model artifacts I could not get rid of as easily as rebuilding)</p> <p>This 40-pin GPIO cover is based on the dimensions of the source thing.</p> <p>The remix is:</p> <ul> <li>4 pins exposed: pins 8, 10, 12 and 14, for use a UART on pins 8, 10 and 14.</li> <li>Ground indicator, for plugin in the UART cable correctly</li> <li><p>Pin1 indicator, so I don't accidentally place wrong side. (as if ;) ) Some people asked me; "why a 4-pin connector on 8, 10(, 12) and 14 while pin 6 is ground as well? could have used a 3-pin connector on 6-10".<br/> My answer is; because now I still have the option of either using or providing 5v from or to the Pi on pins 4 and 6.</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 5</p></div><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>.1</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div><br/> <strong>Filament:</strong><br/> REAL PLA Orange <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>I have printed it with .1 layer height without supports so the bevel is as smooth as possible.<br/> With a .2 layer height, some parts of the bevel have more than 45 degrees overhang, possibly resulting in jagged edges.</p> <p>with .1 layer-height on .4 nozzle, I found I can easily print 70 degrees overhang, but it might not work out for you. (In that case, use supports, or accept the slightly jagged edge)</p> <p>Alternatively, print with the "pins" side down, but I like the glossy finish my glass plate + 3D Lac give ;)</p> <h3> final note</h3> <p>If you like it, click the like (heart)<br/> If you print it; post a make<br/> If you have suggestions for improvements, questions, any kind of remarks; leave a comment</p> <p>Looking at the download statistics, you guys and gals out there really like this thing :) so, leave a like, a make, a comment.<br/> Much appreciated!</p> </div></p></p></p></p> Category: Electronics
