Cloning complex 2d shapes with inkscape, freecad and 3d-printer

This small tutorial will cover how to clone complex 2d parts with a flatbed scanner, inkscape and freecad. You may use this for any complex shapes that are too tough to measure using calipers. This technique can also be used to reverse-engineer complex PCB shapes to aid in creating custom enclosures. As a small example I’ll clone part of my archery fingertab.
