The Spherical Gears CV joint is a free printable 3D model from Thingiverse by 3dMakerKing69. I made this as to see if this mechanism could've been used for my mechanical snake design, but it ended up being too bulky and not quite reliable, so I went with a simple UV. You can download the STL file from the original listing below and print it at home.

About this model

I made this as to see if this mechanism could've been used for my mechanical snake design, but it ended up being too bulky and not quite reliable, so I went with a simple UV joint for that. These are basically two spur gears that their teeth profiles got sweep toward the center of an arch or a sphere, then they are jointly linked with the use of two simple flat spur gears to keep them moving in a rolling joint fashion. All the parts are on one file, just split them up and print them with default settings.
