Wooden Train Stackable Riser/Support (Brio / Ikea)

This is a stackable and rotatable riser/support that is compatible with various wooden train sets. I designed my own as i found it hard to find something similar that was stackable, rotatable, and acted as a tunnel. I have tested the widest carts i have and they are all able to go through the tunnel portion. I print upside down with support. Update December 2024: Some users have mentioned compatibility issues with IKEA train sets. I have made a slight update to the model and tested with a fresh pack from IKEA and it should fit much better now.
