6 - Coin slots
2 - Center Chest Vents
3 - Coin Return notches

Notched Vent
The main body of the notched vent is part of the laser cut skin. These two boxes add the notch to the piece. You can leave the face plate of this vent unpainted and paint the box silver to make it all look metal.
Coin Return Vents
There are three coin returns on the R2 unit. One on the front, and two on the back. This is designed the same way as the notched vent.
