Here is my final version (V3) for a foldable mini GPS - naze Mini - mast for a FPV airplane.
Installed and tested sever hours. This last version overcomes the brittleness of my previous that were destroyed in the bottom part of the mast.
Total height is 65mm from the support good enought to avoid EMF without causing a lot of drag.
Folding movement is allowed only in one direction so during transportation or hard landing GPS may be preserved.
Print Mast1st piece and support with 100% infill - must2nd piece with 20% or less.
Printed in ABS
Sand carefully and check movement. Drill a hole for your favorite screw (mine is M3x20) to keep the parts assembled.
