I figured they would be useful for someone
STMF4 Core cutout. This requires a 2mm washer to go between the threaded terminal (mouser PN 534-7700) and the panel since the discovery board and core board do not sit in the same plane. This also recesses the SD card somewhat but seeing that it does not get removed often, I opted for a small slot for aesthetics instead of a bigger opening to make it easier to get out
For the midi cutouts, you want to use SDS-50J midi connectors (http://www.cui.com/product/resource/sds-xxj.pdf) which have holes in them for M2.5 or 2-56 screws. The holes to the right are for activity LEDs
