Craft produced with precision 3D printing technology for accurate parts and good simulation of engine components. Adjustable rotation speeds and integrated LED lighting to illustrate engine operation and enhance display. USB rechargeable base with included USB cable; the base contains a small power supply system. Battery type dry cell. What is included and how it works Detailed assembly instructions are provided so you can build the turbofan/turbojet model step by step. When assembled and placed on the base, the model runs using the base power supply. The rotor blades spin to demonstrate airflow and blade operation under engine drive. USB cable included for charging the base. Please charge the product before first use. Important usage notes Before using, fully charge the base power supply. When placing the model on the base, align the metal protrusions on the base with the two metal contact pieces at the tail of the model to ensure good electrical contact. Because the product is 3D printed, some fine details may not be . This is normal for PLA printed parts. Material offers strong surface hardness and metallic texture but is not made of metal. Recommended use scenarios Classroom demonstration for mechanical engineering or physics lessons to illustrate turbojet principles and component motion. Hobby assembly and display for model collectors or aviation enthusiasts on a desk or shelf. STEM activity or group workshop where participants assemble the model and learn about rotating machinery and power transfer.
