Large radius compass

Compass based on 3D printed parts (4 in total) which makes use of a string to draw circles / arcs of any size. Additionaly some M3 screws / nuts as well as one M8 nut / one M8 screw (I used M8-16) are required. The pencil carriage was designed to be used with an “eding 400 permanent marker” of roughly 12.3mm diameter.
