Cell Phone Dragon Egg Stand with cord passthrough no supports needed. 90mm wide cutout to accomodate most large phones, Tested up to my pixel 6 pro with otter box case on it. If your phone is larger scale up as needed off that number or Smaller if you have a smaller phone and would like to save material. 2 walls is plenty, i printed with 8% infill but less could be used but it would be rather light otherwise.
