Megadrive Genesis Master System Powerbase Converter Flap Door Cover

As usual, something I needed, so figured other people might need one at some point
I didn't have an original to take measurements off, so this is just a best approximation based from pictures online and trial and error

if you find this useful or intend to in any way use these to add value to something your selling please consider making a small donation, it would be much appreciated for the time/effort taken designing these .....although lets be honest I'm not really expecting it :P
