Great additional Tunnel Set compatible to Hubelino® a Marble run for Duplo®.

Its for marbles around Ø25mm.

You can choose 2x2, 3x2 and 4x2 length. Every object has his own build plate.

After much Test-prints i managed to get the clearance perfect. The bricks should fit like the other ones.

I printed with X1C in PLA+, you can try ABS & PET as well! Share your knowledge.

While testing get some warping, because of that i added a little brim.
