Duplo train hook

Hi, 

My son wanted to connect two trains back to back, as they should be able to run both ways. This needed a connector which i couldn't find anywhere, so I made my own!

Tweaked the dimensions to make it a nice soft snap and a fairly loose fit!

It can hold up a traing hanging vertically but easy for my son to seperate.

This is a fast and easy to print as it is.
