This prop smartphone is similar in general size to a Samsung Galaxy A51, with the thickness of a Samsung Galaxy A33. It isn't meant to look like any particular design.

I do not recommend printing the model laying flat, as that can create a hard-to-remove support structure on the backside, the camera hump, or on the screen. I used a 0.2mm layer height with a 30% infill. Make sure to print in a color that isn't translucent, as I did, or you will be able to see the infill. The included gcode is meant for an Ender 3 Pro.
