Spherical Gears CV joint

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. Here it is in action on my TikTok here https://www.tiktok.com/@autismbawsome0/video/7691364297036942606?is_from_webapp=1&sender_device=pc
