I was after a drip hook/IV hook for the ER (Emergency Department) where I work. Many of the trolleys (gurneys) have a built in hook that is broken, and the cubicles don't often have anywhere to hang a bag of fluids. Matt_M (http://www.thingiverse.com/mark_m) had a design for a similar thing but which required supports to print. This one doesn't and requires no post-processing.
