Nucleo ST-Link Case and Connectors

This is a screw together case for the ST-Link that comes with any Nucleo 64 board. There are also two 'connectors'. These are just holders for jumper cables, to stop you mis-wiring the Nucleo board to the ST-Link.

You need a different connector for each type of Nucleo board, and so far I've only made one for the STM32F303RE.
