A smartphone stand I use for my iPhone 12 Pro Max. It is based on a phone stand by @Sem3D_136548. In contrast to the original model, the set-up angle is steeper here. I mainly use it for landscape mode.
Picture for comparison: in gray is the original model, in pink is my remix.
Depending on your printer, supports are not necessary. You could use tree supports for the overhangs. Also, if you want a smoother finish I recommend using adaptive layer height.
Additional tip: the heavier the stand is, the better (Infill ;))
