Wooden Marble Run STEM Kit
The Fortress Marble Cascader is a wooden marble run you build from 227 laser-cut pieces, complete with 10 marbles. Turn the cranks and each marble travels through a tower distributor, spiral slopes, a crane lifter, and clever switches driven by cogs, gears, and wheels.

Complex Mechanical Marble Track
The fortress design sends each marble on a winding journey through the mechanical track, making the finished build both a working toy and a display centerpiece. Precision laser-cut pieces fit together cleanly for a smooth, satisfying assembly.
STEM Learning Build
This marble run puzzle turns gravity, momentum, and mechanical advantage into hands-on play, making it a screen-free STEM project for kids, teens, and adults. The build sharpens spatial reasoning, patience, and fine motor skills.
