About this 3D model

Brio wooden train bridge supports that uses Duplo lego as pillars. With this collection you should be able to build as complex bridges as you like. 2013-08-18 Update Increased the size of the female part with 0,5 mm because it was a little tight. 2017-12-23 Update Added the SketchUp file so this thing can continue to thrive. Merry Christmas
