Bottom Protector for Owala 40oz FreeSip Water Bottle

thingiverse

Designed to protect the bottom of a water bottle, and fit for an Owala FreeSip 40 oz. This is not an officially licensed design and contains no branding. Compare to Owala's Bottle Boot, which is silicone.The design fits snug with a friction fit. Inner diameter is 92mm, 70mm tall, 2mm thick around the circumference, and 5mm thick at the base for extra cushion. There are two STL files: (1) curves with fillets that mimic the ~7mm radius curves at the base of the bottle and (2) no curves, which is very slightly easier to print and harder to tip.Print in TPU. I used TPU 95A, but you could go softer. Infill around 15%-20% but it only matters mostly for the base. Change wall count if you want the sides to be different softness. No supports needed for either design.Not intended for direct contact with food or water. Owala's Bottle Boot is probably better than this, but here's an option for folks with a 3D printer.
