This is a case for the X6 rom gaming system. I know, odd thing to make.
Maybe someone will use it! Also covers the SD card slot so it accidently doesn't get lost.

I printed mine in PETG and works well to protect against kids dropping it.
Use the slicer software to add a name to the back if you want.
