I create this model, but was heavily inspired by AlwaysTinkering's version. I made this one more contoured to the remote. It's not an exact fit to the remote, but is within a fraction of a millimeter around, so good enough for me. You can print it standing up without supports, but there is a fillet on the bottom corners, so your results may vary. Installation will require longer screws.
The author remixed this model.
More contoured to the remote than the original.
