OpenScad model of a Galician bagpipe chanter.
Measurements of the chanter were kindly provided by Professor Paulo Marinho.
There are two .scad files: gaita_c.scad builds the chanter by blocks, gaita_c_2d.scad rotates a 2d sketch allowing for finetuning and interpolation.
The chanter model 3d-prints and plays in its current condition, but it is slightly low and needs adjustments. If you want an inexpensive but ready-to-use instrument see https://www.ccinstruments.pt/.
