About this 3D model
Lids and spouts for toddler/infant sippy cups do not stack well in the cabinet. For the “Nubby” type sippy cups which are common at Wal-Mart and on Amazon, without handles, this serves as a good holder for the lids. Notes: Does not accommodate the type of cups with handles, however could easily modify the one tower with cutouts to accommodate. the spout fit is tight, but this is to keep the orientation upright for stacking.
