@Allyn The part of this stand that touches the bottom of a phone would require supports, perhaps the holes too. (Assuming it's all printed standing on the thin side.) You can download a slicer and slice with automatic supports, it will help you see which areas would need to be redesigned for optimal 3D printing. Diagonals instead of 90° bends help avoid supports. Of course, you can still use supports if you need an exact, particular shape.
