SCAD Customizable pin header cover with jumper cut-outs

prusaprinters

<p>I started out with a plan to create a Raspberry Pi 3 GPIO header cover with customizable cut-outs for jumpers. The idea was to only expose the pins that are needed and protect the rest.</p><p>In the end i have an scad fully customizable header cover with jumper cut-outs. In addition to being able to select the pins to cut-out for jumpers, you can set the number of rows, and pins per row, and pin pitch. There are also advanced options for tweaking the pin size, hole shape, wall thickness, etc.</p><p>In the original plan I was going to list each pin and let it be set to true or false in the customizer. Once the project became generic, I switched to a list of pin numbers - these also must now be header pins numbers not GPIO pin numbers.</p><p>Since I originally started this for the Raspberry Pi, here are some references:<br/><a href="https://www.raspberrypi.org/documentation/usage/gpio/">https://www.raspberrypi.org/documentation/usage/gpio/</a></p><p><a href="https://cdn.sparkfun.com/assets/learn_tutorials/4/2/4/header_pinout.jpg">https://cdn.sparkfun.com/assets/learn\_tutorials/4/2/4/header\_pinout.jpg</a></p><p><a href="https://www.raspberrypi.org/app/uploads/2014/04/bplus-gpio.png">https://www.raspberrypi.org/app/uploads/2014/04/bplus-gpio.png</a></p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p> </p><p><strong>Printer: </strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p> </p><p>Doesn't Matter</p><p> </p><p><strong>Supports: </strong></p><p>No</p><p><strong>Resolution:</strong></p><p> </p><p>0.2</p><p> </p><p><strong>Infill: </strong></p><p>doesn't matter</p><p> </p><p><strong>Notes:</strong></p><p>I have used fillamentum ASA and a generic PLA for testing. Neither needed shrinkage compensation. The ones in my pictures are ASA @ 0.15mm layer, 0.4mm nozzle.</p><p>There are some thin walls when using 0.4mm nozzles with the default settings. It should slice fine up to 0.45mm extrusion width, but you may need to tweak your slicer settings depending your profile's configuration.</p><p>Since I first published this on thingiverse, I tested it with different slicers. I'm now using PrusaSlicer exclusively.</p><p>PrusaSlicer 2.1.0 slices ok with the default tolerances and default default 0.15mm and 0.2mm layer height profiles where it uses 0.45mm extrusion width.</p><p>Simplify3d 4.1.2 misses some walls with default settings that choose 0.48mm extrusion width. It slices ok with 0.45 and 0.40 provided single extrusion thin walls is enabled.</p><p>Cura 4.2.1 worked fine at both 0.4mm and 0.45mm line widths.</p><p>Be aware that Cura reports the exported stl files as non-manifold while Prusa and Simplify do not. I'm not sure what's going on there but it doesn't seem to affect slicing. It does not happen when exporting directly from OpenSCAD 2019.05 in .3MF format, only when using .stl.</p><p> </p><p> </p><p> </p><p>Category: Electronics</p>
