A simple phone holder I designed for my S20 Ultra. It can hold most smartphones (including case) and has charger cable pass through hole. Great to adhere to center console in your car. I use Cura slicer and used the fuzzy skin setting for some texture. Adjust the size and settings for your phone and application.

Internal dimensions 16mm x 87mm x 96mm - adjust to fit your phone, mine is a larger sized phone.
