Duplo compatible switch track

thingiverse

Friends recently asked if I could create a custom Duplo compatible junction to supplement their child's existing set. In response, I obtained an original junction and created a 3D model based on a scanned copy of the original part, supplemented by precise measurements taken with a caliper. The resulting model is not an exact replica of the original, but it should function flawlessly (alas, without access to a Duplo train at home, I'm unable to test its performance firsthand). Assembly of the model is straightforward: simply print out one STL file for each component. I opted to print the pieces with supports enabled and was pleased with the results.
