I made sdf2stl.saej.in

You can use it design 3D objects with mathematics and bring them into the real world with 3D printing.

You can use it to create 3D models that are impossible to create with CAD, CSG, sculpting, or mesh-based tools.

You can build on a decade of community SDF development on Shadertoy because sdf2stl uses the same language.

A few days ago I may have become the first person to 3D print the equation x^4+y^4+z^4-x^2-y^-z^2+.4=0 (Goursat's surface) https://www.printables.com/model/1713835-goursats-surface

Please try it out and tell me what you think.
