3D printed bottom tray (with quick access snap-on cover)

This bottom mounting tray can be used in conjunction with Ubo HAB adaptor board and allows for quick access to PCIe NVMe or other peripherals to swamp and remove those peripherals without having to disassemble the unit. 

The part is 3D printed and you can also 3D print it yourself with FDM or SLA using the 3D models made available on GitHub.
