Packaging Design Contest Winners

By: Modular Robotics

It’s been a lot of fun watching submissions come in for our Cubelets Packaging Design Competition. We received 12 entries, most via email, although a couple of the submissions were physical, and one was a video entry. Sadly, no interpretive dance entries. We had a great time judging and discussing the relative merits of the different approaches and styles.

I’m happy to announce that we picked Helle Schou Pedersen’s design (above) as the winner. It’s a simple design — a cardboard box with labeling and some cutouts — but it is elegant, sustainable, robust, and inexpensive to produce. Helle sent her entry from Denmark and she’s received a prize of US$1000 and a Standard Kit of Cubelets.

Second place goes to Liam Ward, whose design (above) uses a molded paper pulp inner box with a printed paper sleeve. Molds like this can be made from recycled material, although we haven’t found a supplier that’s interested in making any less than 20,000 boxes of one type. Liam’s design might not be easy to use in practice as the strong magnets would click the Cubelets together, preventing them from sitting nicely in their little holes, but the dividers could easily be removed to allow a solid 20 Cubelet “brick” to nest in the paper pulp. Liam sent his entry from the UK and receives a Cubelets Standard Kit.
