Sorry, couldn't resist the pun. :-DThe mixer bit is done in OpenSCAD, and parametric, including the use of a function to control the position of the channel knobs. Feel free to re-use and make cufflinks or whatever.The cap went for a spin in netfabb's cloud service so that it would load properly in OpenSCAD. I've included it here for reference.This is going to require support material, I think.GitHub repository: https://github.com/syvwlch/Thingiverse-Projects/tree/master/KitchenAidMixerPun
