🚀 New project: a fully functional 3D-printed H-Quad Engine! Printed entirely in PLA, this compact model demonstrates synchronized piston motion in a unique H-engine layout. It runs smoothly, looks great on its custom stand, and doubles as an eye-catching desk toy. A fun blend of engineering, mechanics, and 3D printing. What do you think of the design? #3DPrinting #Engineering #Maker
