I created these phones to accessorize my Sword and Shield cosplay. They're mostly decorative in nature. Because of where the camera on the Rotom Phone is, it wouldn't actually work as a functional case. To get the various elements of this model colored, simply print the phone (in orange filament) and paint the various parts the appropriate color.
The landscape phone measure approximately 188 mm x 168 mm x 11 mm. The portrait phone measure approximately 267 mm x 88 mm x 11 mm.
