I was fighting with jello on my Insta360 Go2 on TinyHawk Freestyle II, designed and tested many many mounts printed with a lots of different materials, that was very long, time and resources consuming process, but finally i think i got it :-). This video was shooed in sunny weather, camera pointed directly do the sun, without any ND filters so conditions ideal fot reveal jello, if you close watcher you will notice some, but i think its close enough to make this footage usable.
It MUST be printed with TPU D30, other way it will not work. Generic TPU will not work on this design.
