This is my rubberband harp, with 15 different notes.
The different tone heights get set by the tension you apply, installing your rubberbands.

For perfect tune, you can use a smartphone app.

It's designed in two halfs, to print without supports (depends a bit on your part cooling fan)       I recommend printing it with variable layer heights, so you get better quality at the top of the parts. This way it should be easier, putting the two halfs together.                                               (for extra clearence i made a tolerance of 0.2mm)

[I put 6mm holes in the bottom, so you can put the knots in]
