@Newtonhal Thanks for the design :)
I don't know much about machining but have access to a CNC router in my local fablab. I just don't know how to convert a STL file into readable gcode for a CNC... (only worked with vector graphics tools like Inkscape to generate the gcode)
I saw your archive with image slices and a settings file. Could you tell me what kind of machine / software it is for and how I could use it?
