Duplo Train tunnel

thingiverse

The duplo train tunnel is no longer sold by Lego, and on the second hand market it seems to me somehow overrated. So my kids finally got to have their tunnel ! And it can also be a bridge if you have the train bridge parts : it's the same height ! The picture above is of my first verion, since then I added inner spacers in order to keep the rails centered inside the tunnel (or the train may hit the walls)
