Turns out my first version of this remote control holder was as flawed as the original I based it on; flawed at least in the location it lives at in my house.
This is my first attempt at a better version, going modular instead of uni-body.
It's okay, but not the greatest thing ever.

Updated to have a curved bottom wing, which helps keep a remote straight while in the holder. More info here: http://wp.me/p2hTaI-16
Print plate without raft or support. I printed with 40% in-fill, which seems like it may be a more than needed.
While the pieces are warm (preferably), slide the arms into the slots. The fit is tight, but they do fit. Sand the base of the arms if you feel they are too tight.
The bottom wing object has a curved recess to allow a curved remote to stay straight upright.
Hang on wall and place remote inside. Defy gravity.
