Hey all,
In the past years I have had an ongoing project – I wanted an ultra-light modifiable electric violin. And finally I can share it with you.
This violin, weighs with all the parts on just 500 grams, which is the same as my acoustic violin. Moreover, the center of mass is close to the player making the violin feel lighter than an acoustic when playing.
This is made possible by an innovation I came up with, and have not seen anyone else do – The violin uses a truss like the one in a guitar neck, letting you balance the weight of the strings and tune the neck. This means that the violin can be printed with just a 15% infill making it ultra light (pegboard box at 20%).
I am not planning to start a violin-building business, so I see no reason to keep this to myself and I am releasing it. I ask you to give me some attribution, and consider releasing your design too. And perhaps a violin 🙂
This is the end result
The design
I made the design with the help of several mechanical engineers that I want to thank – Tal Reindel, Michael Lev-Ari Layoush, Itai Meshorer, and Don Corson. Also want to take the opportunity to thank Yair Grinberg, Oleh Shevchuk. It’s also based on the ElVioin v2 which is under the Creative Commons – Attribution – Share Alike license. So you can use it, share it, modify it and even sell it. But our particular design must also be released under the same license.
You can download the design files here.

Hey all,
Back in 2018 I wrote a blog post about the electric violin that I built. Life got crazy and it got stuck as a draft. Its a really good iteration process, and soon I plan to release a fully open source design I made which is much better than this one. However, this is the first violin I made and despite the sound being iffy, its by far the prettiest. So here is the post about how I made it. I am also adding notes from today, 5 years later. Since stuff has developed and I am in the process of releasing my own design.
So here is the post:
So I 3D printed an electric violin, I wanted to share with you how I did this, what I learned in the process. And perhaps spark a community to share these violins and knowledge how to build them. Arnon Zamir was a partner and we did a mix of research and building together. Dar Abramov did the amazing paint job.
So there is this wonderful project violin designed by David Perry called the F-F-Fiddle. I think the most innovate part is using a carbon fiber rod (originally aluminum) to connect several parts from a 10inch (254mm) and now 8inch (200mm) 3D printer.
The model
David published a pretty comprehensive PDF with the design and assembly instructions. However I wanted to take it a few steps further and do a cool paint job and finish.
First I used Luke’s bout, it was a bit of the mistake because we actually had to cut the guitar keys so they would fit (and that makes them bend a little). The Guitar keys are at the moment the most annoying thing in the F-F-Fiddle.
We really want to change that.
