Lionel Polar Express Curved Track
thingiverse
My daughter unwrapped a Lionel Polar Express train set on Christmas morning in 2016, and we quickly realized this train needs to circle the entire house. So, I whipped up a custom component to match the original set using computer-aided design. The track performs flawlessly. Check out the link to the straight piece here: https://www.thingiverse.com/thing:2004013 I encountered problems with the male ends popping off (non-heated print bed), so I added small support structures at the end to address this issue. You'll need to snip them off using wire cutters.
