RAMPs/Octoprint enclosure

I want to have the Arduino, the RAMPS and Raspberry in the same box. As I can't find it, I poorly design it ...
the enclosure is splitted in 6 pieces, assembled together with M3 screws and captive nuts.

interface with P3Steel will be made with GX12 connectors

DESIGN IN PROGRESS ... More to come after completion, be kind and helpfull as this is my first design ;)
