CocktailBerry MK IV#
The MK IV is the reference build for the CocktailBerry v2 software (the MK III remains the reference for v1). Like the MK III, it moves the wiring onto the CocktailBerryBoard. It is more streamlined and visually appealing, and adds the option to use a scale. The base build also includes two peristaltic pumps, allowing the use of syrup in the machine.
It is fully 3D-printed and designed to be produced on a common 250 × 250 mm print bed.
Beta
This machine is in beta. The build is functional and under final validation; print files and assembly steps may still receive minor changes before release.
