Beginner-Friendly ROKR Puzzle This DIY 3D puzzle consists of 58 pieces, an estimated 1-hour build time, and a difficulty level of 2/6 stars. Great for beginners, collectors, and STEM learners. 5. Multiple Ways to Connect All models from the Industrial City Series, including the ROKR Thermo Engine, are equipped with built-in wireless receivers that automatically connect with other models once activated.

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.

Question:How does the Industrial City power system work? Answer: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.
Question:What are the differences between the two connection modes? Answer: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.
Question:How many connectors do I need for the Power Base connection? Answer: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.
