This is a very simple case for the Mutable Instruments Shruthi-1 DIY synthesizer. Inspired by thing:284637 but completely different and takes only about 3 hours to print. This design includes a front panel design in which you can print out on paper, laminate and glue to the front. More info is provided on: http://diycrap.blogspot.no/2015/02/building-enclosure-for-mutable.htmlIt cant be simpler than this. The OpenSCAD-file is provided. It is easy to change the openings for the buttons etc in case your buttons are of a different size. By the way; the Shruthi should ideally be powered by 9V DC although the panel design states 12V :-)
