Quadcopter Stilt (Square Rod 8mm)

This is a very simple Quadcopter Landing Stilt for square rods with an 8mm inner diameter. I use them on a 1.3kg Quadcopter.
Printed with two shells and 100% infill for stability. Make sure to enable "Generate support material" in Slic3r.
(Some pictures show a slightly older version. I made some slight modifications to improve stability)
