Do you have a phone? Do you have a keyboard? Would you like your phone slightly elevated and tilted to fit well enough beside your keyboard on something that has had barely any refinement?
This model is absolutely nothing fancy and was just made so that I had something to hold a Pixel 7 Pro beside my keyboard at a height and angle that helped to use it as an external number pad. The design has sections for the camera bump and charging port, but also has the top section removed to fit whatever phone with a similar width. The boxy shape isn't much for looks or filament efficiency, but does make it much easier for bed adhesion.
