This adapter allows you to connect a spray head to a 250 ml alcohol bottle. The idea is to maximize the use of alcohol to disinfect surfaces or objects.
There are two models for bottles with different diameters.
The thread was designed to work on several spray heads, (tested on five different models).
The adapter must be printed according to the "PS" image, with PET-G preferably.
