Summary Thanks to Stepan83 for the Elviolin. http://www.thingiverse.com/thing:745940 its design has inspired me. In this version: I modified some parts to facilitate printing without supports I have given a different and modern look. And I've added a integrated chinrest support. All parts can be printed without supports, except for the chinrest Recomended printing parameters: 5 Shell thickness. 4 top down solid thickness. 20 to 30 % infill 0.20mm. layer heights. If you print on ABS filament, you can use acetone or PVC pipe glue to bind the parties. If you print on PLA, then use a epoxi glue. You can use a sanding papper and patching paste for automotive jobs to leave a smooth surface to paint on color of your choice. Dont forguet to use a primer paint before the application color. you can find on ebay the electronics. Find as electric violin pickup. Use a 9.5mm threaded rod as steel core to stronger the violin body.
