Our Story


3DuxDesign is a true family business. Growing up in the Klein household required a good bit of creative thinking and improvising. Every year, holiday gift-giving had one rule: 

"The best gifts are made with our hearts, our hands, and any materials already in the house.  They are not bought at a store."

So while millions would flock to stores seeking the best Black Friday deals, the Klein kids would rummage through the recycling bin for raw materials and head into the basement for extra cardboard boxes to start constructing gifts. It was truly amazing to watch odds and ends transformed into townhouses, parking garages, pinball machines, Kitty-Kingdoms and Hamster Havens. Yes, even the family pets were involved.

The 3Dux ethos is that the best gift we can give our children is an active imagination and the freedom to create. Without pre-set rules and instructions (conspicuously absent from our modeling kits), children will learn to improvise, experiment, fail, reexamine, and succeed.  These are the skill sets that will aid them through life challenges.

With the 3DuxDesign Architectural Kits we encourage your children to experiment with form, function, creativity and deductive thinking.  Our curricula extend from k4 through middle school and are based on design thinking and engineering concepts with a focus on community, communication, empathy, and creating a sustainable world.  We challenge kids think about how good design can make a better future

Ayana has been building the 3DuxGlobal platform over the past two years with a goal to support STEM learning in communities around the world with limited access and to foster an awareness of the diversity in communities and cultures across the globe. She spend winter break 2019-2020 in Haiti, teaching children in the Kay Ang Orphanage. She is currently spearheading the Global Futures Program where students will use 3Dux materials as they imagine, design, build and present their ideas and visions for a better future. 


Ayana is currently a junior at Washington University in St Louis, and matriculated into the Olin School of Business to learn the skills needed to continue to grow 3DuxDesign.
