Dev Update 25-Sep-2020
The enclosure prorotype arrived on Thursday evening 24-Sep-2020, I was excited to find that everything fit absolutely perfectly!
Prototype enclosure
The photos show the prototype enclosure, with the 30m QCX-mini prototype installed.
NOTE: the buttons only protrude maybe 0.5mm from the enclosure; the final production model will use taller buttons that protrude maybe 2.5mm (0.1 inches).
Installation
Photos with each end panel removed, show how the QCX-mini is installed in the enclosure. The top (LCD) PCB slides into the PCB guide rails in the top half of the enclosure extrusion. The bottom PCB is bolted using 11mm spacers to the top PCB. It is slightly narrower than the top PCB. The Controls PCB is bolted to the bottom PCB.

Comparison with QCX and QCX+
Some comparison photos of the QCX-mini next to the QCX and QCX+. The QCX is in the BaMaTech enclosure.
