I'd just like to say, as the designer of Jedimatt42's 32k memory expansion board for the TI-99/4A, these 3D printed cases for it are great!
I would have suggested one design change, and that would be to have the LED window in the front.
Regardless, c0d3m4st4, your work is excellent. Thanks!
I was thinking exactly of that for the new FinalGROM99 case... LEDs are bright enough to be seen even if they are 1 or 2 cm inside the case.
Glad you like the one for your awesome board
