I’ve been using Blender to play with CNC. Blender isn’t normally recommended for CNC design but in the case of classical string instruments it is pretty good – the shapes are all curved surfaces.

One of the trickiest elements of a classical string instrument is the scroll. This was intended to provide a place for the instrument maker to show off their carving skills. It took me a while to figure out how to do this in Blender so I thought I’d share it here. I’m not a Blender expert so maybe there is a better way; however this works for me.
