Cat Food Bowl Risers

My cats are getting older, so I thought to rise their food bowls for them. 

Info online says bowls should be about 100mm (4") from the ground to the bottom of the bowl. 

Two models to fit my bowls, could be scaled to fit different size bowls. 

1. Small - 106mm (~4.17") diameter bowl under the lip, ~38mm (1.5") tall - riser total height 140mm (5.5")
2. Large - 131.5mm (~5.17") diameter bowl under the lip, ~44.5mm tall - riser total height 146mm (5.75")

The hearts are holes to save on filament and printing upside down puts a 45" overhang to print easily without supports.
