Mango Pi tube case

The idea was to create an electronics enclosure consisting of just one printed part. Assembly requires small tweezers, screwdriver, long thin rod and a bit of patience - it is "not trivial, but not hard". I have successfully tested both versions (with open and hidden pins) on Mango Pi MQ-Pro board, it will likely work with a Raspberry Pi Zero 2w, since it has a similar form factor. Parameters like "`wall thickness`", "`case padding`" and "`connector padding`" can be adjusted in OpenSCAD Customizer.

BOM:

• 8 M2 nuts;
• 4 M2x6 screws;
• 4 M2x12 (or longer) screws;
• 1 25x25x7 mm 5V dual fans;
• 2 XH2.54 female connectors (required only for "hidden pins" version).
