Introduction: 3D Printed Marble Machine by Maher Soft

This is a 3D Printed marble machine on our latest Indie 3D Printer that takes marbles through crazy loops and turns. A marble machine designed in ONSHAPE is completely based on rigid bodies, rigid body joints and mechanics. The assembly has approximately 34 parts printed in ABS , and it can be powered by using DC motors or batteries. It uses a 1.5 cm diameter steel marble, which starts at the bottom, and goes to the top, and then returns to the bottom, making this trip about 8640 times in 24 hours.
