CocktailBerry MK III#
The MK III is the successor to the MK II and the reference build for the CocktailBerry v1 software; the MK IV is the reference build for v2. By moving the wiring onto the CocktailBerryBoard, it achieves a noticeably smaller footprint while keeping the full feature set of its predecessor.
It is fully 3D-printed and designed to be produced on a common 250 × 250 mm print bed.
Released
This machine is released. The full set of 3D-print files (STLs) and the assembly guide are available.
Specifications#
| Property | Value |
|---|---|
| Dispensers | 8 × membrane pumps |
| Display | 7" integrated LCD touchscreen |
| Controller | Raspberry Pi 3 Model B+ (newer models also work) |

| Enclosure | Fully 3D-printed (fits a 250 × 250 bed) |
| Dimensions | ⌀ ~240 mm × ~550 mm (H) |
Because the touchscreen is built in, the v1 app is the natural fit, but the machine can also be run with v2.
