Owala Bottle Boot (32oz & 40oz)

There are a couple Owala bottle boot designs out there. I wasn't satisfied with any of them so I modelled one up with thinner walls, a chamfer on the bottom to help with printability and an optimal diameter.

I have made 2 sizes to fit the 32oz and 40oz bottles and can confirm they fit. 

You may need to scale the model slightly depending on material and printer.

I used Overture High Speed TPU, both pink and black, with success. 

Works perfectly with my Car Cup Holder Expander.
