DNA/RNA Building Toy Set with Improved Joints

myminifactory

Remixed from the original design with improved features by chemteacher628, this DNA/RNA building set offers students a better way to learn about DNA and RNA through interactive play with toy blocks. Designed by Ana Wallis, a PhD student from the Nieduszynski lab at Sir William Dunn School of Pathology, and myself for outreach activities in local schools supported by St. John's College, University of Oxford. This remix was inspired by chemteacher628's original design. The new joint allows blocks to snap together from the side, with built-in tension enabling a generous tolerance that works well on most desktop 3D printers. A chamfered edge at the joints compensates for the 'elephant foot problem', reducing tolerances and making it easier to fit pieces together smoothly from both sides.
