Dice Stacking Cup

My son wanted to try out Dice Stacking. (If you want to know how to do it Instructables have a page about it here: http://www.instructables.com/id/Basic-Dice-Stacking/ )

So this is just a basic Dice Stacking Cup. Large enough to let you stack 5 casino sized dice (19 mm). If you need the dice as well I have uploaded that as well.

Updated:
With files with thinner walls in different thicknesses upon request. The original upload has 2.4 mm thick walls. The new files has 2.0, 1.6, 1.2 and 0.8
