Hourglass dice tumbler using 70mm jars

At the boardgame meetups, many folks have been bringing glass jars as tumblers to roll dice. Great idea - no mess or anything.... BUT, I just had to take it one step further, didn't I? With this nifty gizmo, each time a turn passes, someone just flips it upside down (like you would an hourglass) and the dice roll is randomized through the baffles in the center. I think it's neat... and this makes my 100th item on Thingiverse. Yay!

Here's a quick demo on youtube:
