PS2 Brook adapter holder

Holder for a pair of Brook adapters so they don't just dangle there in front of the PS2. If you don't know, the Brook adapter allows you to use Dualshock4 wireless controllers with your PS2. When the adapters just hang off the edge of the shelf, the bright red LED aims directly at you and it's very distracting.

This is the first thing I have designed and modeled from scratch. I am new to CAD modelling and 3D printing. If you think of improvements to this design, please contact me.
