How to make it.

1. Print and cut

   Print all three pages at 100%. Cut the outer track and support outlines. Leave the center of each track floor uncut.

2. Fold the troughs

   Fold the two long dashed lines on each track section upward. For the bendable pieces, also cut the short slits in the side walls so the floor can bend gently up or down.

3. Join the track

   Overlap the shaded JOIN floor area by 10 mm and tape it flat to the next section. Join wall tabs where practical; keep tape ridges out of the rolling path.

4. Build the supports

   Fold each support into a square tube and glue its narrow side tab inside. Cut between the four feet, fold the feet outward, and tape them to a base plate and a rigid board.

5. Set a gentle slope

   Tape a track floor across the top of the 90 mm column, pass it over the 60 mm column and end on the base board. Add braces and extra tape where the track flexes.

6. Test and adjust

   Release one marble from rest. Smooth raised joins, reduce steep drops and add support where needed. Print extra track and columns if you want to extend the run.
