I am on a continues journey in search for maximum simplicity. This phonestand nearly reaches this goal. It works in portrait and landscape mode with smartphones and small tablets.
This build was done on a desktop cnc-machine by Stepcraft from 20 mm wood using a 3 mm spiral toothed flute.

Keep in mind that I can not verify the stl-file as I don't own a 3d printer!
