Infinite double Marble run

Model Overview & Print Notes

Infinite double Marble run This model cost me a lot of effort, finally after many modifications I am satisfied with it. I hope you will like it too. The model has two types of drive - manual or electric. The N20 motor is used with low speed, 50/min . Replacing the drive is easy, just change the cover for a specific sub . The other parts are identical for both types. You can glue the elevator body and track parts together For the spiral and tracks parts, use a wide brim when printing!!! I optimized the model for steel balls with a diameter of 8mm . They can be purchased in a regular Armyshop as ammunition for a slingshot. It's a good idea to put at least 12-15 balls on each side so that the ones at the bottom keep pressing on the ones at the beginning of the elevator.
