Lionel Polar Express Straight Track

My daughter received a Lionel Polar Express train set for Christmas. We both came to the conclusion that this train needs to go around the entire house... so I CAD'd up a compatible piece for the set.

Track works great.

Here is a link to the curved piece:

I was having issues with the male ends lifting (non-heated print bed) so I added little structures on the end to help with that. You'll need to cut them off with some wire cutters.
