ST Nucleo 64 Case

I wanted a case for an ST Nucleo 64 development board, but all the ones I could find required screws to hold the board to the case. I wanted a friction fit that could easily be removed from the case when needed (and which didn't require additional parts).

The ST Nucleo boards are designed to use Arduino shields, and are also designed to fit (sort of) Arduino cases, so I found an [Arduino case](https://www.thingiverse.com/thing:1876393) with pins to hold the board and mixed it with an [ST Nucleo case](https://www.thingiverse.com/thing:1859561) so that it would fit, but not require screws.

Since the Arduino Uno board is smaller than the ST Nucleo 64 board, it will also fit in this case.
