The mounts I have designed are now for sale. Each set is individually designed for the specific tablet for perfect fitment and easy install. Right now I have sets for 1st gen Nexus 7, 2nd gen Nexus 7, and the iPad mini. 3M tape holds the mounts on. If you want to remove the mounts it takes a good amount of force but the tape doesn't leave behind any residue or marks.

I can change the design of these mounts for other tablets if I get enough interest. So far it has sold very well to the Nexus and iPad mini family.
