This is a 3D printed modular vending machine.

Each module comprises of 3 parts: a back piece with the motor mount, the middle section and the tray to catch the dispensed chocolate. These modules attach together using M3 x 8mm bolts to form a tray.

The legs also comprise of 3 parts: the feet - which support the bottom tray, the extenders - which is required for each additional tray you add, and the handle - which attaches to the top and adds rigidity to the structure.

These modules can be mounted in any configuration, such as 2x2, 2x4, 1x8, 3x3 etc.

The coils are made with 3mm aluminium wire and have a diameter of 55mm. These can be made to any dimensions depending on the items being dispensed.

The vending machine can be controlled via an App or Alexa using Wi-Fi switches connect to an Arduino.

Each module is 60mm wide and 280mm long. The largest part is 150mm x 60mm x 60mm.
