Underlay for working with paint spray cans

thingiverse

I enjoy working with PLA, easy to work with and the color can be easily changed with the spray can. Like everyone else, I place the component on a piece of cardboard and start printing. However, sometimes it happens that the color creeps underneath and sticks the component to the cardboard. Inspired by the underlayer in laser cutting or water jet cutting, I quickly wrote a small script to create a pad with minimal contact area. To my surprise, the files become enormous due to numerous circular calculations. That's why I'm publishing only the script here along with a small demo version. In OpenSCAD you can modify all key parameters. Have fun.
