Summary

This mount is designed to hold an Android Nexus 7 1st Generation
Tablet for use in the "Raspberry Pi Door Strike with Android Display"
Instructable. This thing was made with Tinkercad.

Instructions

After printing this thing on a 3D printer to the desired thickness
(.1mm looks really nice, but there are not any small details so
slightly larger layer thicknesses work just as well) place your
Android Nexus 7 1st Generation Tablet inside the mount and secure it to a wall using drywall screws.
If you wish to use this mount on a tablet other than the Android
Nexus 7 1st Generation Tablet, feel free to remix this thing by
resizing the interior dimensions
