This is a TPU mount for the Eken H9R HD Camera on the HSKRC Freestyle 250 True X frame. This frame is a Ummagawd Remix clone but because an angled camera mount is built on to the frame, the GoPro Hero4 mounts available for the Remix can't really work on the Freestyle 250 unless you've got an extra horizontal front standoff. This camera holder eschews mounting on the standoff directly in favour zip tying to the built on mount.

TL;DR; I've fixed the jello video I was experiencing with this TPU holder. I've added a V2 design with some improvements, but the V1 design can also be made to work:
The root cause of the jello seemed to be the foam pad which comes with the Freestyle 250 frame, on top of which I mounted the TPU camera holder, which unfortunately still allowed for quite a bit of play/vibration where they contacted each other, even with the zip ties pulled very tight. So I removed the foam pad and mounted the TPU holder directly to the milled alloy angle plate. I also added an additional zip tie at the back of the TPU holder, perpendicular to the two holding the unit in place. This reduce a bit of left-right wiggle I noticed. Finally I tightened down the screws on the pivot axis through which the frame normally hinges apart for servicing.
I noticed there was still a tiny bit of front-back wiggle at the front of the TPU holder where it allows the camera to over hang the base slightly. I flew fine with this, but the V2 design adds a flange to fix this as well as an extra perpendicular through-hole for that other zip tie I mentioned above. With the addition of the flange, there is no way to print this without supports. I recommend turning on supports Touching buildplate only instead of Everywhere in Cura.
