GPS tower for Skywalker 1900/1800/1600

This object is composed by 3 parts that together form a GPS tower and protective case for an RC plane Skywalker 1900/1800/1600 (2016) in the place that was supposed to be to placed perhaps a pan&tilt small fpv camera. I decided it was mor apropriated for a GPS antenna.
The case was designed to perfectly enclose a chinese Happymodel GPS antenna powered by M8n Ublox receiver that came with my Pixhawk clone.
The case is composed by the top and bottom parts and should be tightened with 3 M3 screws
