I made this so I could watch/use my Galaxy Tab A in the shop. It is NOT free standing you need to screw it to the surface for it to work.

Gives access to front buttons, but not others as much. Just needed a basic holder and had some trouble finding one.

Print as oriented.

Also, it holds the device with the case that I have.
