Cover for the TalonSR speed controller. Should be useful to protect the electrical contacts from debris. Holes on top for LED, 3-pin PWM port, fan mount screws and airflow. Should be attached via the same holes to attach the Talon just use longer screws. Built-in spacers should prevent you from cracking the enclosure if you overtorque the screws. One stl file has the team number 2172 embossed in the front, the other is blank. This was designed in Creo3.0 Let me know if you want the prt file.
