Mini DIN-9 breakout board case for DB Electronics MD-90SM Breakout

This is a very simple remix of "PC Engine Duo to HDRetrovision Adapter Casing" by MobiusStripTech for their MD-90SM breakout board, shortening it to make it suitable for the shorter MD-90SM breakout board by DB Electronics (https://github.com/db-electronics/MD-90SM-breakout-kicad). Thank you for allowing remixes!
