Clem rebuilds the 3D Chameleon MK4 from the ground up, replacing the legacy electronics with a modern ATtiny3226 controller, TMC2209 drivers, thermistor-controlled cooling, and clearer status indicators. The mechanical system stays true to the original open-source design, but the updated hardware is easier to assemble, easier to source, and designed for reliable multicolor filament changes without modifying your printer’s firmware. The full project, files, and code are available on the element14 Community: bit.ly/3Y66qRC
