I wanted an under the shelf PS3 controller holder, but found ShaoPellini's design had slight gaps on my PS3 controllers that left a slight wobble.
The hole allows for the charging cable, and I've found if I stick the charging cable through both holes it will hold the cable without interfering with holding the controller when not charging.
I liked ERA_Evil's form-fitting holder, but it was meant to be mounted in a different way than what I needed.
merging these two files was a total hack job of manually merging vertexes, so it doesn't line up perfect but prints just fine.
Prints great with no supports
Prints great without supports, mine was with Colorfabb XT.
