This is a document camera stand that uses a cell phone. The 3D printed parts are the base and head. Hardware parts are described in the post-print assembly notes.

The head slides open to accept an average-sized cell phone for use as a document camera. It has cutouts for cables and holds the phone securely under the tension of 2 rubber bands. Users seem to be able to use it without instruction.

It can be set up to hold the phone facing down as a doc cam, or also swivel up to be a conferencing camera. It securely holds most phones.
