Summary

This is a tutorial is how to convert a screenshot image to a 3D printable STL file.

Hit the screenshot button on your keyboard.
Paste the screenshot into GIMP to isolate the section you want.
Now paste the isolated section into Inkscape, so we can turn it into a vector.
From the SVG vector file import it into Tinkercad and make sure it's printable, export to STL.
At this point you can go find a 3D printer, but it's always better to share your work. I like to upload my 3D files to a site called Thingiverse. You will never know what your contribution to open-source might turn into, who knows it might even cure a disease or fly us to the moon.
