This is a remix of granmaito's excellent DB9 to DB9 box, modified to fit a Joymega adapter produced by Monster Joysticks (Sega Megadrive gamepad to MSX/x68000 adapter). I wanted an enclosure for my adapter, so I very roughly modified granmaito's design to snugly fit the adapter. This is also my first adventure into CAD, so it's not perfect in any way or form.

The bottom is mostly open to allow the solder joints to poke through and keep the enclosure small - also reduces print time. The lid is notched to allow for Megadrive extension cords to plug into the "to MSX/x68000" port. Superglue the lid to the base along the edge and you're good.

HUGE thanks to granmaito for his DB9 to DB9 Box!
