I purchased a cheap Android tablet from Walmart for use as a screen to control Octoprint, (specifically the 100011886)[https://www.walmart.com/ip/onn-10-1-Tablet-32GB-2020-Model/248528865]. After carrying it around a couple times the constant setting down and picking up of the device made it apparent that it needed to be mounted somewhere. Given my current setup, a wall mount would not be very convenient, and the ability to reposition also seemed rather desirable.

I have mounted other devices on microphone arms in order to be able to quickly move them into and out of position, and this seemed to be another use case where that would be a fairly ideal solution.

This bracket is designed to minimally obscure the front screen (and, in fact, does not obscure it at all). It also permits access to all ports and functions, as it is intended to be permanently or semi-permantently installed. I created the case / mount in three pieces in order to fully enclose the tablet. The center piece accepts a hex nut and stud for the microphone arm mount. This design allows for the center piece to be flipped (stud pointing up or down) as well as different mounting options simply by changing out the center piece.

After printing I cleaned up all of the sharp corners and edges and chased the holes using a small drill bit. After post processing, the left and right halves of the case are slid over the tablet, and then the center piece is installed and the assembly is screwed together with captured hex nuts and flathead machine screws. The three 1-1/4" screws go in the middle, and three of the 1-1/2" screws go on each of the top and bottom.

I have included the .stl files for each of the three pieces, as well as the Sketchup file containing all three pieces.
