Oh, hello! I didn't see you there.
My name is Daniel and I am a recent graduate from the University of Northern Iowa Mathemamics Department. While there, I conducted a two-semester research project in a branch of low dimensional topology called knot theory. That's how I got my start making 3D printable models of various knot theory objects. Every model in my shop was designed by me using a combination of Python, OpenSCAD, and Meshmixer.
Feel free to send me a message if you have any questions.
