Nắp đậy cho chai muối, tiêu và gia vị khác

Simple covers for bottle of salt, peper etc.
It is strange, but even I tried bottles from same set of glass bottles, those have different diameter.
Because of that I had to print with 3-4 scales 100%-103% and then choose which fits better. 
You should hear “click” and cover shouldn't fall out.

I used PETG, PLA can broke.
