A simple case mount for a Fantin SD Board which doesn't come with any Mount holes.

Post-Printing

After printing, tap a thread into the 3mm hole (my printer always prints holes about 0.2mm smaller, otherwise 3mm would be too big) with a metal M3 screw. Use a Nylon M3 x 5-10mm screw to secure the SD board in the mount. Screw the mount to the backside of your case panel. Done!
