A functional Gifford-McMahon cryocooler was successfully built using 3D-printed parts and simple components. While initial prototypes reached -84°C, design choices like using air and acrylic limited performance, but the magnetic piston mechanism proved effective. Future iterations will utilize helium for improved cooling, demonstrating accessible cryogenic technology for hobbyists and researchers.
