Marble Machine G4 – Assembly Kit

G4 Huge Gear Lift - Build it. Play it. Display it

The G4 Huge Gear is a unique wooden kinetic marble machine, crafted from high-quality natural solid wood. It features a large gear system that lifts steel marbles to a height before releasing them to roll down through Marble Run modules. Powered by a robust yet whisper-quiet motor running on 3 AAA batteries (batteries not included), or optionally with a DC adapter for direct power connection, it ensures continuous operation without the need to replace batteries. Measuring 17.3x14.5x12.5 inches (440x370x320 mm) and weighing 8.8 lb (4 kg), with its substantial size and weight, it’s an impressive display piece for spacious settings or a unique gift. Here’s what makes it exceptional:

How it works

G4 Huge Gears Lift is composed of two main parts

• Part 1, the G4 Base Machine
• Part 2, consisting of two Marble Run Modules. See the specific illustration below for details

The Marble Run Modules come in a total of 9 unique designs for you to choose from, as illustrated below

These modules are interchangeable, allowing you to swap their positions with one another. This flexibility enables countless setup variations simply by rearranging the modules. Typically, selecting any two modules is sufficient for a fully functional setup. For instance, combining the G4 Base Machine with Modules 1, 2 or Modules 3,4 works perfectly. However, you can opt for more or even all 9 modules if desired. The illustrations below showcase some ways to arrange pairs of modules for references:

• G4 Module 1,2

• G4 Module 3,4

• G4 Module 6,7

• G4 Module 8,9
