Designer's Journey

At the time it was invented, the Thermo Engine represented vast progress in industrial machinery. It made work easier, changing daily life, business, and mass production workspaces. It was safer, more compact, and more reliable than the early, bulky steam engines that were unstable to operate. In the same way, building a ROKR model quietly changes something in you and your routine. Those miniature 3D puzzles you build actually turn your screen time and restlessness into calm, focus, healing, and tangible displays you can interact with. Both the Thermo Engine and the crafting hobby are actually massively helpful, creating a highly positive impact in different ways in our lives. Celebrate more life- and world-changing inventions with ROKR's Industrial City Series.

Description

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.

Thermo Engine Features

Three Main Modules

This device depicts a cylinder module, a pulley module, and a flywheel module.

Burning Power

An orange glowing cylinder simulates steam engine combustion.

Simultaneous Activation

Power these Industrial City devices in sync with their 2.4GHz wireless connection or the 6-way power hub.

The Thermo Engine's Process

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.

How does the Industrial City power system work?

The Industrial City series supports two connection modes - Track Link and Wireless Link.
Both modes require Type-C power input.
With the built-in wireless receiver, you can activate all connected models at once, or link them through the powered track base for synchronized operation.

What are the differences between the two connection modes?

In Track Linkage Mode, all models are powered through a 6-way power track, linked to a single Type-C input for synchronized operation.
In Wireless Linkage Mode, each model is powered individually by Type-C, allowing for a flexible layout with a distance of up to 5 meters between models.

How many connectors do I need for the Power Base connection?

You’ll need one connector for each model you want to link to the Power Base.
For example, if you purchase three Industrial City models, you’ll need three connectors.
Each connection set includes a six-way power base and a dual-headed Type-C expansion bridge.
When connecting multiple models, one dual-headed bridge will remain available for future extensions.
Note: Connectors are sold separately.
