this is a case for raspberry, not really final but works great like that.
i suggest you print the light bloc first, the add leds and cables, then, when you print the case, add a pose at line 100 (for 0.20mm print detail) and put the lightbloc gently in the front of the case, i will bne easyer to mount.
for the loghtbloc i add 3mm led 5v // and add a cable to the gpio 3v and ground
screws are m2
the raspberry support is made to use screw+nut
