Sega Genesis / Mega Drive USB Daemonbite Enclosure For MiSTer FPGA

The goal was to design a minimalistic enclosure that would allow for inclusion of an arduino pro micro board (ATmega32U4) and OEM Sega Genesis / Mega Drive style controller port. The design is based on a USB-C version of the arduino board. The arduino board has a snug fit - please be sure your arduino board will fit properly. It's possible some arduino boards may use slightly different sizing.

Printing Suggestions:

Material - PLA

Enclosure base - I recommend printing this component with the flat surface on the print bed. Layer height .14mm first layer and .20mm remaining layers. I used 15% infill. I only used supports for the 4 screw hole countersinks. I did not use supports for the USB-C port cutout, however depending on your printer, you may want to enable supports for that as well.

Enclosure top - I recommend printing this component with the flat surface on the print bed. Layer height .14mm first layer and .20mm remaining layers. I used 15% infill. I did not need supports for the angled edges.

Adapter Parts Used: 

• (1) Arduino Pro Micro board (ATmega32U4) with USB-C connector (board dimensions: 35mm L x 18.4mm W x 1.65mm H)
• (1) Female DB9 (D-Sub 9) controller port
• (4) 12mm M3 hex screws
• (1) 5mm M1.4 screw
• (4) 5mm M3 brass screw inserts
• 22 gauge silicon wire
• 1/8" ~ 3/16" shrink tubing

Adapter Assembly Instructions:

I have also created a YouTube tutorial video featuring assembly of the adapter and setup from start to finish.
