…I wanted a user to be able to simply plug and play with the case without requiring any desoldering/soldering of components.
Parts were designed and modeled in CAD and FDM 3D printed. The parts required sanding due to the layer thickness of the 3D print.
Once sanded, the parts were primed and spray painted. A slider mechanism is used to cover the cartridge bay if it is not being used.
A single USB port is routed to a hub at the front, with a second USB port converted to a mini USB and routed to the top of the case. Ethernet and the remaining 2 USBs are still accessible from the side. The HDMI and power are at the rear of the case. Solder-less header pins are used to provide connection for the the reset switch. Light pipes guide the LEDs from the board to the front-top of the case. Each cartridge has a mini to standard USB connection to plug in a small profile USB stick which hold the OS.
