Ball circuit with steps 315pcs - 3d wooden mechanical puzzle

Ball course with steps - Modular mechanical model

The Ball course with steps is the third part of Ugears' Marble Run modular series. This complex machine combines precision engineering and wood aesthetics to create a dynamic circuit inspired by Rube Goldberg devices. This advanced level model offers an immersive experience, from careful construction to hypnotic pleasure of perpetual movement.

Engineering and racing mechanism

This 3d puzzle is distinguished by its sequential lift and its three routes with unique mechanical challenges:

• The three-level elevator: An ingenious level palan that raises the balls sequentially to the top of the circuit.
• The escape trap (track 1): An interactive mechanism or three balls must collaborate; the third ball releases the second, which in turn unlocks the first.
• The roller coasters (track 2): A fast track designed for smooth descent and maximum speed.
• The waterfall ramp (track 3): A descent on four levels exploiting gravity for a regular rhythm.
• The swinging arm: Located at the base, it sorts the balls and returns them to the elevator for an uninterrupted cycle.

Modularity and interconnection

Designed to evolve, this course is entirely modular and can be integrated into a giant circuit:

• Interconnectable system: Thanks to the included connectors, this model can be connected (front or side) to the other tracks of the Ugears range (up to 4 models).
• Flow control: A trigger lock allows the balls to be directed to the internal cycle or to an adjacent connected track.
• Single propulsion: In connect mode, the entire system can be operated by a single crank.

Technical specifications

• Number of pieces: 315 elements.
• Level of difficulty: Advance (Expert).
• Mounting time estimates: Five.
• Accessories included: 10 colored balls, wax and glass paper for lubrication.
• Structure: Chassis strengthens for optimal stability during operation.
