Eachine Tiny 32bits F3 Brushed Whoop Mount with Camera Holder
I liked the original design but it wanted to combine it with a cam mount and also didn't need the battery holder bar at the rear, also some real snap-in feature was missing for the fc requiring to tape it down.
So I designed it from scratch in openscad fully customizable with all I was missing.
Thanks a bunch to vegos for the original design, which made mine much easier to accomplish
Print it in ABS and you can bend it slightly to clip the FC in place. Works a treat.
Weights <= 1 gram or so if I recall correctly.
