Parametric Breakout Board Sockets (ESP8266 NodeMCU, Arduino Nano, etc)

prusaprinters

<p>Every time I build a little electronics project, I hate how the components usually just rattle around in the case. So I designed this customizeable solution in OpenSCAD that lets me configure the number of pins, the sizing and spacing, etc. Now I drop one of these into just about everything I design. It prints just fine at 0.3mm in PLA, with 2 perimeters, and has a nice, snug fit. (Although I would consider using a higher-temperature filament if I was expecting to generate much heat.)</p><p>And if anybody's curious about those little triangular holes on the sides, those are to allow me to get a probe onto the pin-legs if/when the top of the board is inaccessible. (But they can be turned off in the OpenSCAD file if you don't want them.)</p><p>To add one to your project, you can just print a socket and glue it into your already printed case. You can even add them to existing projects that suffer from “chip rattle". Alternatively, you can import a socket STL to your case design and print everything all at once, so long as you can print it with the socket oriented flat, as shown in the photos.</p>
