This is a remote control holder with multiple configurations.  Please do not print files that has a demo in the file name. I am currently traveling and haven't had a chance to print this yet (saw the contest and thought this was a decent idea). Demo files as the name suggest are for demonstration and are meant to show how to put the various parts together.

No supports should be needed if you orient the base on its bottom and the control holders on their back.  There are stl's for a stopper when the caddy is open (2 for the outside and one for the inside).  When the caddy is closed, you can store the stoppers at the storage on the top. 

I'll suggest gluing the hinge stopper at the end of the hinge.

Enjoy and let me know of any modifications that will make it better.
