This is a clean RPi 3 B+ case. I created it taller to make room for a on/off switch and custom LEDs.
I used 20mm M3 bolts for the case and 6mm M3 bolts to secure
...さらに表示 the RPi inside the case.
EDIT 8/30/18: I switched the side the bolts are installed. This way you can use shorter bolts and then the heads double as feet for air circulation.
