Summary

Ibox-z3 is a chassis with extension board for orange pi zero 3 (https://ibox-z3.ru/).
In this case we have only one reachable from outside USB, so i used USB extension cable (also that may be a hub with soldered cable) to break out another USB.
So that requires a hole in the chassis, and there is a custom back panel with it.

m3d files are Компас-3D models, i can give a STEP if required.
