Vertical Steam (air) Engine

My entry for the Maker World "Physics Education Design Contest" is a vertical steam engine designed to demonstrate the principles of mechanical motion. This compact and functional model is optimized for 3D printing, requiring minimal supports and a total print time of just five hours (120g filament). It can be powered by compressed air or, with proper lubrication, even by a vacuum cleaner. Key FeaturesThe engine’s design reflects a vertical setup, showcasing the timeless beauty of steam power. It operates with a power rod that transmits motion to the flywheel and a control rod that manages the steam flow. These components work in harmony to illustrate fundamental engineering principles in a hands-on, engaging manner. Assembly/BOMsee assembly_guide.pdfHow Does It WorkThe vertical steam engine functions through the precise interaction of two vital components: the power rod and the control rod.Power Rod: The power rod connects the piston to the crankshaft and plays a crucial role
