Being refreshedWe’re updating our project images and write-ups over the coming weeks.

Cutaway render of the dispenser unit: an orange cylindrical casing with the pump and electronics inside.

Smart Water Dispenser

A pump unit that sits on a 19-litre water bottle and fills the dispenser for you, so nobody has to lift the heavy bottle again. Taken from first concepts to a finished, 3D-printed product.

No more lifting

  • Section view of the unit, showing the pump chamber and the electronics compartment.
  • Exploded, see-through render of the casing’s stacked layers, with a lid marked Do Not Touch.

Swapping a 19-litre bottle onto a water dispenser means lifting about 19 kg to chest height. This unit stays on the bottle and pumps the water up into the dispenser instead.

Sealed, stacked and modular

  • Render of the electronics layer: the microcontroller board, relay and regulator on a printed plate.
  • Section render of the bottle mount, with the sensor housings and the pipe connector.
  • Assembly drawing of the bottle mount, with its parts list.

One enclosure holds the pump, the microcontroller and the power regulator, and it’s designed to keep water and air out.

The casing is a sandwich of layers that print and assemble separately, so each one could be changed and tested on its own while we prototyped. The mount on top of the bottle carries the sensors and the pipe connection.

Printed and assembled

  • The printed prototype: a red pump casing, a white mounting ring and a black base.
  • Red printed parts of the mount laid out on a cutting mat.

We worked end to end, from the first concepts to the finished product, and printed the parts for every prototype.
