About this model

This is a 3D printed piece that works as an interconnect between Duplo bricks from Lego and Brio wooden train tracks. I was inspired by but after trying out a print, I found it too difficult for the 3 year old to put the tracks on, and I decided to make my own, slightly simpler design. It's designed in OpenSCAD and I have uploaded the .scad file along with the .stl file, so that you can easily modify as needed
