Small & Light GPS Sensor Tower

I needed a small, lightweight tower mount for my M8N GPS sensor for a 250 quadrotor.
This fits in a simple 15mm hole in the frame. Sandwich the quadcopter frame between the bottom of the tower base and the disc clamp. One screw holds it in place.

you can route the wire through the slot in the base, running it inside the V-shaped tower column and holding it with a zip tie or two.

Print the pieces, glue the column to the base and the upper disc with superglue.
Voila!
