Summary

The F-F-Fiddle (pronounced eff-eff-fiddle) is a full size electric violin that can be made with common home 3D printing equipment. All parts can be printed without support material on a Makerbot Replicator 2 or larger (I also use a Type A Machines Series 1), and the total material cost is roughly $250.

Here’s a video intro to the F-F-Fiddle: http://youtu.be/8NDWVcJJS2Y and here’s the FIRST tune played on a FFF 3D printed violin! http://youtu.be/_0-8EZPDshY

8/15/14: I fixed a problem in the part orientation for the Bout and Neck that caused an issue with the first layer. Prints are much easier now.
7/7/14: I’ve made two F-F-Fiddles in ProtoPasta’s carbon fiber filament — they sound better! All of my bridges are now CFPLA, and I highly recommend using CFPLA for your parts. See pictures, above.
5/6/14: New bridge designed to send vibration more directly to the pickups. New bout part has counterbore for Gotoh Stealth guide/accent parts. Not necessary for functionality but they look nice.
4/2/14: STEP file for the instrument has been uploaded.
4/1/14: I changed the Rev numbers for the Bout files to 7. There is no change to the part, so Bout-R6 is OK to use with Neck-R7.
