3Dprinted Operable DIY Turbofan Engine Model Size: 27 x 7.8 x 10.2 cm Overview A precision 1:18 scale, buildityourself turbofan engine model that combines realistic mechanics and visible inner operation with modular assembly. Designed for handson learning, detailed display, and engineering demonstration. Key benefits Handson learning and clarity: Open, transparent casing and moving parts make it easy to see and explain core turbofan functions and airflow mechanics. Ideal for classrooms, hobbyists, and study groups. Realistic operation without complexity: Motordriven fan blades move like a working turbofan, delivering a clear visual demonstration of rotor dynamics and component interaction. Ready to assemble and durable: Comes as disassembled modular parts with the required tools and screws for authentic assembly. Components are precision 3Dprinted for consistent fit and tested for extended use. Features Modular engineering design with disassembled thermoplastic parts. Material noted as thermoplastic with components derived from corn starch, cassava roots, or sugarcane. Scale 1:18 to represent the core mechanics of a modern turbofan engine. Motordriven fan blades that operate under realistic motion. CFD simulations used in design validation and 200hour durability testing completed. Battery powered with one included battery. Runs up to 30 minutes on a full charge. Transparent casing to reveal internal mechanics during operation and display. Includes two tools and multiple screws for assembly. Packaged in a box with dimensions 33 x 18 x 14 cm. Net weight 600 g, gross weight 850 g. Recommended age 15 years and older.
