Game Boy Cartridge Cover for Power Supply

My remixed version of "GameBoy Zero Cart Hollow" by mattiasbrandt.
I've made cutouts for a power supply board and USB cable.

This is designed for a build using an HDMI screen. That's why the power supply board is not sitting at the top of the cartridge to leave some room for the HDMI connector.
