3 axis Roll Hitch for Crawler Trailers

I needed a Drop hitch to go from my truck to the trailer so I just designed my own 3 axis hitch.

You'll need:
2 M3x8
1 M3x20 (trailer tongue to hitch)

Make sure the hitch moves freely, if not, then you can use a 1/8" drill bit to bore them out if need be. Just be careful not to go all the way through on both sides of Hitch 2 and Hitch 3 because they are designed so the M3 bolt will cut threads into one side so no nuts are needed.
