Got tired of looking for my controllers all the time since I didn't have a specific place to store them. Decided to make some arms to mount them on the side of my game rack so they would be in arms reach when I grabbed a game to play.

Edit: I have now added numerous options for the base and arms. Including flush mount arms and base plates with the screw holes on top.

The arms should easily slot into the base, the force of the screws holding the base should be enough to keep them in place. The model has holes sized for two #6 screws.
