This is a simple drop in replacement for the original Sega Saturn cartridge door. It's designed to print easily without supports on FDM printers. There are three parts, the cart door, left arm, and right arm. The arms slide into the cart door and are held in place by friction, so your 3D printer should be dialed in before printing. Optionally, use the variable layer height “smooth” feature in your slicer (Orca in my case) to help smooth out the steps on the top of the cart door.
