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.

Indie: The Desktop 3D Printer
We have attached the instruction document along with spare list and drawing for rod. Please refer the documentation. NO SUPPORTS NEEDED! Some parts might not fit on a small print bed, we recommend you to cut the file in 2 parts and glue later. 15- 25% Infill worked best for me. 0.2 mm layer height. Try out the best settings for yourself. Steel ball bearings Go3d
How I Designed This
At first glance, it may look relatively simple, but a lot of planning and tweaking had to go into the design process keeping in mind that all parts have to be 3D Printed and support free to avoid any kind of post processing. It took us approximately 2-3 weeks to design the assembly on Onshape and a series of iterations to make a working model of the marble machine.
The whole assembly consists of 34 3D Printed parts, nuts, screws, and a DC motor to provide a rotary mechanism. The marble starts at the bottom, and goes to the top, and then returns to the bottom, making this trip about 8640 times in 24 hours. Each step lifts the marble back up to the top of the slide in a synchronous manner. Here, the entire process starts all over again and continues so long as you keep turning the CAM shaft.
