In a world where many kids spend hours on tablets and other screens, a Connecticut company is encouraging them to put down the iPad and start building.

Bridgeport-based 3Dux Design creates cardboard-based modeling systems that help children learn through hands-on play at home and in the classroom.

The company grew out of an idea from founders Ayana and her brother, inspired by Ayana’s experience studying architecture. There, she discovered how creativity, science and technology come together through hands-on learning.

She believed exposing children to that kind of experience at a young age could spark an interest in STEM careers.

The system uses six specially designed connectors that attach to cardboard, allowing children as young as 3 to build everything from simple shapes to complex structures while learning concepts such as angles and engineering design.

The products are packaged and distributed at the company’s Bridgeport facility, where orders are assembled and shipped to schools and families across the country.

For the team behind 3Dux Design, the most rewarding part is hearing from teachers and families who see students developing problem-solving and collaboration skills through creative, project-based learning.

“We love hearing feedback from teachers in the schools that use our product,” Ayana said. “It really builds those human skills through project-based learning.”

At-home kits range from a build-a-bot set to a rocket ship and even a home with LED lighting.
