I've taken the excellent Atari 2600 cartridge shell from norm8332 and added the appropriate notches to accommodate the Atari 2600 UNO flash cart. The version I have specifically is the 2018 Electrotrains version with the full-size SD card. I received a printed shell with the device from the Brewing Academy but wanted a different color with a higher print quality.

The main drawback with this is the lack of two top screws means the top isn't completely held flush, but it's not a big deal. Use the same screws that norm8332 recommends with the original model. In my print here I went a little large and caused some stress on the bottom, but I'm too lazy to print another.
