Use case:

I wanted a development-compatible vertical stand that works with Raspberry PI B boards and doesn't interfere with the optional CPU cooler. You may also use it as a desktop, if you like the naked visual of your Raspberry.

The pin works with a tight fit, if you don't have M2.5 screws. Make sure to tune your XY compensation for a fit you like.

Printing settings:

PLA is recommended, but nearly anything will work. Prints without a support. Prints nicer with 2 walls than with 3 walls. The board is mounted using 4pcs of M2.5x16 (or shorter) screws that screw into the plastic hole directly. You may use attached plug pins, but the M2.5 screw is the better option.
