Summary

Inspired by David Windestals design from flite test. I use silicone tubing to hang the mount from my quad copter. See photos.

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/e9vjlpW3ofq

Instructions

Printed with PLA,10% fill and .3mm layer height

Other parts

8 - 4 X 20mm bolts

8 - 4mm nuts

Silcone tubing cut to length that you desire

Cut silicone tubing to length you require
Insert 4mm nuts into silcone tubing with bolt - insert far enough that the tubing covers all of the nut but the hole
Insert 4mm bolts through holes in the base and scew into the nuts in the tubing, the tubing will get pinched between the nut and the mout securing it.
Use the 4 counter sunk washers to attach the tubing to your frame again the tubing will get pinched between the nuts and the washers.

The mount will hang from the multirotor isolating it from vibration and elimiating the jello effect.
