Ikea Lillabo or Brio Duplo Pillar connector.

You can use the original duplo bricks for the pillar.

My modells, such as:

TrainTrack IKEA LILLABO Ramp Dualside l:250 h:70mm

Train Track IKEA LILLABO Ramp length:250mm, h:70mm

Among my models you will find several other constantly expanding railway tracks, you should look around among my models and download them.
If you are satisfied with my work, please, in addition to downloading the model, printing and evaluating it, you can also support it with boost.
