 I designed a 3D model for a cap enclosing the large open glass bottles we have for some ingredients. It is a 2-color model that can be printed with a dual-nozzle printer, or you can just leave out the "filling" and print it with a single-nozzle printer. The design [can be found in my Git Repo](https://git.xythobuz.de/thomas/3d-print-designs/src/branch/master/cocktail-maschine).

 ## Arduino-Cocktail
 
 Custom built 3D printed [bottle cap adapters](https://www.thingiverse.com/thing:2445858) are used to pressurize coke bottles and take out the liquid.
 Everything is controlled by an Arduino, with a small OLED display and three buttons as the user interface.
