Iris Door Box

I designed this in the early days of 3D printing - around 2013. Probably better versions out there now, but here it is.

There are 3 different diameters and 2 different heights of each. Due to tolerances and dependance on the hardware size, you won't have too much luck scaling the box, thus different sizes included. 

Simply print 1 of each file for a particular diameter and height. See the included PDF for assembly directions.
