Marble Kit V

This modular marble set was created mainly to have a small marble run on the desk and distract for a while to set up the circuit and throw the marbles.

I have spent more than five years modifying this project to create the perfect circuit and looking for the best way to join the pieces together and make it easy to print.

The pieces are printed in PLA with 0.2mm. No supports are needed, they are already included in the model.

Marble:
The circuit is designed for marbles of 11mm diameter. I usually use metallic marbles, their weight allows the marble to go faster.
