Pyrex Lid Holder Stack

I was tired of the large number of Pyrex lids falling all over the place. The lid holders out there hold them sideways, which doesn't allow stacking and are space inefficient. So I designed these 3 prints for Pyrex lid holders. One for 1 cup, 2 cup, and 4 cup. The three stack with each other, fitting under a a standard kitchen cabinet height. (Multiple prints of the same size will not stack.)
