GoPro anti vibration mount for multicopter ETC

UPDATED NOTES-
Experiment with different earplugs, the ones i have been using seemed to have hardened and are not as efficient as they were when new. use all 8 O-rings, seems to be more effective. i will revise this slightly soon, to reflect a few things i`ve noticed when in use

GoPro anti vibration mount for multicopter ETC
uses 12 earplugs to insulate the vibrations from the camera.
its specific to my quadcopter but it could easy be adapted to use in different senarios.
it has 6 holes for M3 bolts to give options for fixings and it comes with a backing plates which can be used for fixing also.
it also requires O-rings, minimum of 4 needed. maximum 8 needed
O-ring size 15mm I/D 2.5mm thk
