I have my Gameboy color and games displayed in a cabinet, but my Game Boy Printer was was gathering dust in a drawer since I didn't have a nice stand for it.
Make sure to use supports from the stand and print everything straight up.
Ensure your stand doesn't have insane elephants foot and just push it into the slot.
I've used Shapr3D to complete build this model from scratch. I've included all the 3MF files if someone else wants to perfect/change this design. The model was heavily inspired by the Gameboy Printer Stand, created by DrHood on Thingiverse.
