Tiny bottles - 4 designs

Here is a set of small bottles (about 3cm high) of different shapes. They are designed with internal chamfers so you do not need any support (neither internal nor external) when printing. It was just a fun project as my kids like small bottles to store tiny stuff.

The bottles can be printed bottom-up, but the cap should be printed upside-down. I have tried with PETG, PLA and TPU.
