The notable feature of this iteration is that it is able to produce shapes for 3D printing or CNC milling.
Demakein can currently design flutes in a number of styles. I will be adding other instruments such as shawms and reedpipes in the next few weeks.
Demakein uses the the nesoni tool writing framework to provide a collection of tools that can either be run from the command line or from Python, and that can be easily customized by subclassing in Python. For example you could subclass one of the flute designer tools and adjust some of its parameters.
