lorawan RAK831 Raspberry Zero Gateway Case

I have build a RAK831 LORA Gateway based on Charles Hallards 1.4 PCB, which you can find on GitHub. For this gateway I designed a housing. Cover and base case fixed by 4 M3 countersunk screws. In the base case I pressed 4 5mm long M3 brass thread bushes to hold the cover. The spacer (Unterlegscheibe) and 2 M2.5 screws keeping the zero pi parallel to the pcb.
