JLink cap

The Segger J-Link debug probe has 20 pins. In my experience, I've only ever used 4-6 of those pins. Also a lot of times I don't have the luxury of using a breakout board to be able to use the 20-pin ribbon cable and end up using jumper wires. Instead of having to memorize which pins are what, I've designed this cap to block the pins most commonly used, so that I only have to remember a few. This also helps to stabilize using jumper wires.

It is recommended to print this at as high quality a setting as you're willing to print it in.
You can print it in 0.20, but unless you're printer is really dialed in, you'll have to open up some of the holes post-process with a 0.5mm drill bit or some other method.
