Hammer and Sickle by Arsen6331

This is a hammer and sickle, the symbol of communism. I created it by getting this SVG: https://commons.wikimedia.org/wiki/File:Hammer_Sickle_Star_red.svg, using Inkscape to remove the star, importing it into FreeCAD, converting to a sketch and padding the resulting sketches (two were created).

I used open-source software (Inkscape and FreeCAD) to make an STL file of a hammer and sickle and then 3D printed two of them. I figured I should share it for anyone else who might want it.
