Duplo Train Coupling / Hitch

Have you or your little ones ever wanted to attach a Duplo train to another Duplo train only to find out that the hitch is only one way?

Don't worry, this model has you covered!

This simple coupling allows two “male” hitches to be connected to each other.

Printing instructions:
