Can Stacker

My wife was annoyed that a certain, well known brand of canned food (begins with 'H' and ends in 'Z' are not designed to stack vertically, leading to a tsunami of cans falling from the cupboards at the most inconvenient time.
This is a simple ring, with internal flange, which is designed to be placed on the top of a can, and locates another can on top.
If this has been done before, I apologise. This is my first upload to Thingiverse.
