Mini Marble Music Machine Melody Maker

This is the OpenSCAD model of the music cylinders for Rossero's Mini Marble Music Machine, so you can implement your own melody.

 If you don't know what the Marble Machine is referring to, watch Wintergatan's Marble Machine.

The first item in the customizer (parametric model maker) is for defining 9 different characters (e.g. letters) for the 9 notes of the xylophone bars. It's preset with the 9 notes used in Rossero's machine (GABcdefga, I used capitals for the lower octave), but you can change that, as long as you use 9 different characters.

Below that there are the available 64 beats of the cylinder, organized in 8 bars of 8 eighths each. You can enter notes for your melody here (the characters defined above). You can enter more than one note each beat.

Repeated (consecutive) eighths of the same note will not be played; they'd be too fast for reliable marble restocking anyways.

 I uploaded 3 OpenSCAD scripts: 

• an empty one

• one preloaded with a simplified version of Wintergatan's Marble Machine melody as an example.

• a variant for a ¾ or 6/8 time signature with 8 bars of 6 beats each.

 Printing: Standard settings should be fine.
