GoPro to Ram ball mount.

Updated to allow for a m4 button-head screw for extra strength.

Based on https://www.thingiverse.com/thing:53438 for the gopro base, with the mesh cleaned up a bit.

I had to add 1mm of length to get it to correctly fit (goproram_longer.stl) but it might be a bit loose in some gopro bases.

It has a hole modeled in, in case you wanted to heat up and thread a m4 button head screw in. I've never had any issues with strength without the rod, however, even after using it to hold my phone onto my bike for years.

The .blend model has a bunch of boolean based mods. You can disable the hole by disabling the *screwhole booleans, for example.
