This is a simple camera mount for Realacc 210 v2 and maybe also good for Lantian 210 frame.
I used it for my SjCam SJ4000+
It can break if you hit a concrete wall :) but easy to print more of this item.
I used support for the bottom bridge but it might be bridged, too.
Camera lens protector recommended.

Infill can be adjusted to durability vs. weight :)
