This is a little case I designed for the Pimoroni hyperpixel round and raspberry pi zero.
To assemble you'll need:
Screw the interface plate, Pi and screen togeather
Insert SD Card and USB cable and place assembly into the main case
Route cable out the back and snap on the base
Press the cover ring into place (print in a contrasting colour for a bit of pop).
