I had Claude create a script for FreeCAD using my specifications. This shape is the basis for a manifold that I am using to develop spiking-neural-networks. I'll drop the script below.

I posted this one before. I'm not trying to spam or anything, the previous post was just way too busy and I spaced out on being able to edit it.

It's shaped the way it is for a reason, but it's also just a neat torus. It has a helix in it. Maybe try to print sideways with a raft and interface ironing. IDK. My top and bottom looked like trash.
