After nearly completing the gameboy zero with the helpful tutorials I realized something; the innards were too fat for their own good also the battery would never fit, So I poorly designed this spacer.
I also realized that I have no cad software experience or a 3d printer available so instead of letting it go to waste I give the blueprints to the Sudomod community for them to use. The measurements should be correct but since I never got a chance to test it who knows.
If anyone does try it out a note: it is meant to be assembled around an existing gameboy zero and glued to the top panel of the gameboy.
