![]() Because the connectors are small, they are considered a choking hazard for younger children. All connectors have been proven safe for use in all children over 3 years of age. Our products are tested for mechanical strength, sharpness, breakage, lead, phthalates, soluble metals and and a number of chemicals that we cannot pronounce. Our cardboard is die cut and hand packaged with care, exclusively by the 3DuxDesign team at our Bridgeport Workshop.Ībsolutely! Our connectors and even the cardboard has been third party tested by an independent certified facility that specializes in testing children's products sold in the USA, All components exceed USA CPSC government standards for child safety. The cardboard is sourced from our buddies down the street at Valley Container. We have since moved on to injection molded connectors made right here in the USA less than 100 miles from the 3Dux Workshop. The owner Bill and the rest of the team (even Ashton-their dog) have been instrumental in helping us from the start and their product is superior grade. They were made with PLA exclusively from COEX, an American company based in Wisconsin. Our original 3D printed connectors were made in-house (literally). There is a lot of physics and engineering in these seemingly simple connectors! Starting with Ayana's detailed drawings of connector options, Ethan, a freshman in high school at the time, taught himself CAD and engineered the exact geometry that makes our connectors flexible enough to adapt to a range of cardboard thicknesses, snug enough to grab, and smooth enough for little hands to easily assemble their creations. 3DuxDesign sold over 3,000 architecture sets and printed over 100,000 connectors before moving to injection mold! (For the math whiz, that would be 277.78 continuous days of printing, 24 hours per day, 7 days per week, assuming that the printer never gets clogged.) Sparked by an AP Physics summer assignment and a summer at Columbia University School of Architecture, 3Dux cofounder Ayana Klein decided to design a product that allows children to repurpose discarded materials in the home in a thoughtful and aesthetic way while blending 3D spatial concepts, geometry, and engineering with art and creative play. Wanting to break out of more typical uses of 3D printing in rapid prototyping, she set out to offer the community a truly functional product that can be manufactured with this technology. Brainstorming original concept of selling 3D printed connectors was a true family exercise.
