This is a PS4 controller mount I made for the same "Clip System" I made for my headphones. (here: ==>>http://www.thingiverse.com/thing:693980)
The main base clips onto the glass table, then the mount part slides into that clip and the hooks press fit into the mount. With a series of main base clips made, you can move the mount all over the place by simply sliding it out of one and into another.
Update: enclosed the push fit hole to be more robust; created a new base with leg locations spread more so legs wrap outside of the controller sticks. This makes the holder much more reliable and the controller does not easily get bumped off like it used to.
