Physical Product

This marble machine 3d prints in one piece. No need to make any adjustments. Just import file into your slicer at 100% scale, slice, and send to 3d printer. 

(We use oxidizing agents to give the copper PLA filament a nice blueish-green patina.)

The automatic marble machine is powered by one 5V DC motor and a drive gear mechanism.



Material: PLA

Extruder Temp: 200

IMPORTANT DISCLAIMER: Please note that 3D printing results can vary due to factors such as printer models, slicer settings, and materials used. It is normal for there to be slight variations in prints, even when printing the same model multiple times. With 3D printing, it is to be expected that there may be imperfections, as this is the nature of the printing process. While I make every effort to ensure that my models are compatible with a wide range of 3D printers, it is possible that some prints may not work as intended. However, most issues can be resolved by adjusting slicer settings or re-printing, and in some cases, slight modifications to the printed parts using tools such as sandpaper, hot glue, or a soldering iron may be necessary.
