Objects for the Nic Multibahn with nibbles for Duplo figures and other Duplo & Lego things. https://www.nictoys.de/produkt/multibahn-6-teile/ Should also work with other brands with tracks of slightly different measurements such as Eichhorn, Trihorse, Beluga etc. Not all variants printed and tested. OpenSCAD source included so it should be easy to correct if necessary.
