A hula mixer?

I needed a project to test the dual extrusion on the new 3d printer. and I wanted a hula. 
It Hulas! This was a very fun, small project for the new 3D printer. I was thinking about interesting lab-related projects I could print, and I realized that even used hula mixers were surprisingly expensive. While it is not quite as feature-rich as some of the others on the market, it works great. The base was printed out of PLA in one shot and TPU was used as the support interface material to make support removal significantly easier. There are several features within the model that would present a problem for PLA support material removal and I wanted to use the dual extrusion function of the printer I have. Within the housing there is a NEMA 17 stepper, a small controller and an arduino running a very simple loop to rotate and shake. If there is any interest in something like this, I'm more than happy to throw the design files and code up on thingiverse.
