GoPro Mount Extension - Four Sizes

I needed something to use with my GoPro Clamp-On Mount to raise the camera up to bed-level. Once I got started, I made several different sizes:

100mm
75mm
50mm
25mm

The 75mm and 50mm are in the pic., shown with my GoPro Mount - Short Knobs. Combine these as needed to create an articulating arm to place your camera where you want it. If you need one, here's a GoPro 90 Degree Adapter that matches.
