Bigger Soft Bottle Drying Mount

I made https://www.thingiverse.com/thing:6442288 for the 1L Hyrdapak.

I like the bottle and got a 3L version.

This is the same idea but bigger, keeps the bottom upside down and structure supported to facilitate drainage and drying.

It should fit any bottle with an opening measuring an inner diameter of 32mm and an outer of 42mm

Again, consider using a food-safe coating, or material, or sterilizing periodically to prevent bacteria build-up.
