3D printing knobs and potentiometer extenders

Using FreeCAD ( FreeCAD: Your own 3D parametric modeler ), I designed a potentiometer knob and a potentiometer shaft extender for the preamplifier I am building. The models are parameteric so that you can change the shaft diameter, flat size, etc. for your particular project. I have included STL files for a short extender that works with standard 6 mm diameter potentiometer shafts and knobs.
