Revisit history with the Thermo Engine, a mechanical concept that represented rapid industrialization worldwide. This dynamic, LED-lit ROKR 3D puzzle features a beginner-friendly 58 pieces and an estimated 1-hour build time.
Compact power packed within a single machine, the Thermo Engine is one of the inventions that helped drive widespread industrialization. ROKR's version creates a replica of this classic single-cylinder engine, demonstrating mechanical energy transmission through a moving piston, a rotating flywheel, a rear pulley, and a glowing light indicating active combustion. Build this 3D puzzle yourself, then activate it with the built-in wireless receiver to sync it with other models in your Industrial City setup. Whether you're drawn to history, mechanics, or simply love working with your hands, the Thermo Engine is a close look at how these breakthrough machines once powered the world forward.
This device depicts a cylinder module, a pulley module, and a flywheel module.
An orange glowing cylinder simulates steam engine combustion.
Power these Industrial City devices in sync with their 2.4GHz wireless connection or the 6-way power hub.
The piston pumps, causing the flywheel to spin. A belt links the flywheel to the rear pulley, carrying that rotation onward and smoothing it into synchronized motion.
