Show HN: Portrait-Outliner: Automatically create line drawings from photographs (github.com)

Hey everyone, I'm a mechanical engineering student, and this is my fun side project. I made this library so anyone with a 3D printer can make robot-drawn pictures of their friends.

My open-source design is inspired by the $7500 draw-me-bot: https://fotomaster.com/products/draw-me-bot/ (:

It's still very much a work in progress, so any tips or suggestions would be welcome!
