This is a fully printable case for the fantastic Zynthian project:
All visible parts are rotated so that the external side is the first layer (on a glass bed this make a fantastic look).
Overhang are less than 45° so all parts should print without support.
You can thread (M4) holes on the tabs in left and right side, or glue nuts in place.
(Yes, I know, screw holes on the back panel are almost out of the tabs... I'll fix that ASAP)
