3D model description

Here is a model I developed to make a marble circuit using the principle of the famous Penrose staircase.

Circuit developed for Ø13 mm balls.

The zip folder contains the STL files of the circuit as well as a list of components that you can easily find on Amazon.

To see this ball circuit in action: https://youtu.be/-7huzq5VjJ4

3D printing settings

This ball circuit is composed of 4 ramps in particular.

Dimensions of the highest ramp:

L 206 x W 36 x H 121 mm

By placing the ramp diagonally, the print volume can be contained in a cube of 166 x 166 x H121 mm thus printable on a tray of 200 mm side.

Printing parameters:

0.2 mm per layer

1 mm wall thickness

15% filling
