Geared coffee sleeeeve

I liked the coffee sleeves that Sethmoser (thing:99020) made but it needed something else...like...GEARS!! This coffee sleeve has a gear mechanism that rotates. Play with your coffee!
I designed this in Rhino as a fun sunday project and is my very first attempt at making something with gears.
Here is a video of it in action!!
