eClarin is my project for making open source electronic aragonese bagpipes. It is based on eChanter (http://www.echanter.com) project. and of course, open source too. Here's a chanter model to print. Maybe you want to watch a little video of that stuff working http://www.youtube.com/watch?v=N7JBUeyA3bY You can view the code and repo at https://github.com/danielmartinez/eClarin I will add links documentation and instructions to make that.
