These connectors expand to allow to put cardboard in and then that return to their original shape once cardboard is in to tightly hold it.

really nice idea. the best for me.


I like this! It solves the problem of securing the cardboard. But how do you make an L connector like that? Or a T connector?

About This Project

Concept Phase

In this project, we want you to submit sketches, images, videos, and other visuals that illustrate industrial design directions for Michael Muscarella’s Cardboard Connectors.

We’ll use the top concepts as a starting point for our continued ideation, sketches, sketch models, etc..

In this round, you’ll want to examine the possibilities of what this product could be, including what materials we can use to make the item. Think about whether it’s a system of parts or a whole product, or what the buying experience could potentially be. We’re looking to select several winners to form the foundation for continuing onward!
