This is a handle/bracket to hold a GoPro if you're following some action with RC cars or if you just want a 2 handed grip to help steady and smooth out follow motion.
You'll need 2 or three of the grips, 2 Base Plates (top and Bottom) End bracket is purely for esthetics.
Additional hardware:
6 x M8x10mm bolts to hold brackets to grips
2 x ¼ 20 screws for the top handle bracket and base plate connection and for the base of a GoPro mount.
1 x ¼ 20 nut for the top handle bracket.
I used 4 perimeters and at least 4 top and bottom layers this should give enough bite for the scress to thread into.
This can also work for smaller cameras like the Panasonic GX9 or Olympus E-P5 or similar sized cameras although haven't tried to use it with them yet.
