This is a remix of the excellent OpenSK Key Enclosure by rightbrainelectronics on Thingiverse.
This remix shortens the entire case by 1mm so it's more tolerant of USB ports that are a little recessed (like laptops), puts the OpenSK project logo on the back of the case, and covers the LED holes with a thin layer of plastic.
Best to print in a slightly translucent filament, or do a filament change above .5mm to make a nice two-tone case.
