I use an old tablet in the garage for dart scoring and until I got a 3d printer for Christmas I had it mounted with a couple binder clips. The main problem with the clips was that the power button is on the back of the tablet, and I couldn't access it without getting the tablet out of the clips. You can use screws or nails to attach this to whatever surface you're mounting to.

Printed with eSun PETg @ 240. 5mm Brim on all parts.

Rotate the bottom brackets on their closed ends (see picture) and you'll only need supports from base plate. Hinges broke free with minimal effort. I had to wedge an exacto between a couple fused layers on one or two prints.

Rotate top clip on it's side, no supports, 50% - 75% infill.
