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.

Updates

Updated V.9 (04/08/2026)

New set: rail set

Marble

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

Jointing system

The pieces are joined together in two ways: sideways to make the circuit and vertically, so that the circuit can grow upwards.

Set

Elevator set

Structure set

Acrobatic set

Rail set

In this section I will put the new pieces by sets. I do it this way to be able to organize the pieces in a better way and to know which pieces the users like more and thus to be able to know which pieces to create before.

More parts coming soon
