This is remix of original "Ender 3 all in one, universal rear electronics case" from Michael from Teaching Tech channel.https://www.thingiverse.com/thing:3688967
I've update this model to use with Orange Pi PC, and 2 DC-DC converers, standard 80x80x32 Fan from PC.
Also you can use old version for Lids to use with two 12V fans.
