FrSky D4R-II stacking 36x36 tray with integrated (print in place) folding antenna tube holders. When extended, antenna leads lock into place at 45deg from the multirotor in the horizontal plane. And when folded, should conform with or into multirotor body. Tray stacks on top of Naze32-type flight controller. Requires antenna tubes... use hot glue (or super glue/CA+) to secure. Print directions: TIP: A little lubrication on the antenna leads will help movement in and out of antenna tube. This is a remix of the original D4R tray. https://www.thingiverse.com/thing:444796 UPDATE: Use v12 for best "print in place" results. Use a pick free the rotating posts (PIC 1). The antenna tube holder portion may be fused to the tray, use a pick to free (PIC 2).
