Forearm rocket launcher

My own 3d printable design of Iron Man's forearm rocket launcher. To build yourself you will need 3 servos, an arduino nano and some jumpers, standard laser diode(optional), toggle switch, battery snap, 2 nails, a drill, super glue or model glue, a bit of aluminum stock, and an inch diameter hole-saw drill bit. the sizes are based on my forearm so you may need to edit the size of the bracer rings to fit your particular wrist.
The arduino code is the attached word doc, the lift servos used to raise the platform are two separate servo motors with all wires joined to act as one servo, whereas tilt servo is a single servo used to increase the angle of launch to around 30 degrees to ensure the rocket clears the launcher. Servo values may vary depending how you build it.

wiring is simple, servos and laser all lead to a common ground on the board, I used the other ground for the battery snaps negative, I used 3v3 to the toggle switch to the laser diode. lift servos trigger wires lead to
