I created this model and printed it using a monoprice iiip 3d printer.
fits the command strip for picture frames that holds 16 lbs, but that is assuming you follow the directions and use 4 strips rather than 1 like I am.
strips:

fits my Subaru outback keys nicely.
painted poorly because i use a soldering gun to flatten out the areas where the supports where so they are super smooth, but happen to discolor the plastic.
i can make this for other keys if there is enough demand.
