Zojirushi Water Bottle Bottom Bumper

This is a protective flexible TPU bottom bumper for the Zojirushi insulated bottles. It should fit the 12 oz (SM-SA36), 16 oz (SM-SA48), and 20 oz (SM-SA60) models. These bottles have a small flare at the very bottom. 

I printed with a .6 mm nozzle, 2 walls, .3 layer height, 5 floors, 5 tops.
