A recent message on Twitter about an open source 3D printed violin sent me in search of more information about Hovalin. Much of the 3D printed universe is about robots and drones, so seeing a violin in the mix caused me to pause and wonder more about this unique project. I reached out to husband and wife team, Kaitlyn and Matt Hova.

Kaitlyn is a developer, professional violinist, and a neuroscientist. She believes "that art and science are most impactful when they inform each other." Matt is a developer, electrical engineer, and interested in music production. He is a big fan of open source projects that are made available through sites like Thingiverse.

Hovalin's files are available on the website and GitHub, and the project is licensed under CC BY-NC 4.0. I asked why they chose that particular license, and Matt said they weren't sure the best way to license their project openly, so they took their cues from FFFidle, another open source violin project. Recently, Kaitlyn and Matt have released version 2.0 of Hovalin.

"It has a more accurately designed body and is easier to assemble thanks to building the truss rod parallel with the neck's build surface. The Hovalin is not the greatest violin in the world, but (in my opinion) it’s the greatest 3D printable acoustic violin project around today," he says.

They have plans to release version 3.0 soon. And they are currently working on plans to develop a recorder and a ukelele. Their goal is to focus on two or three of the easiest-to-make musical instruments in order to create a STEM music program based around 3D printing.

On others contributing to Hovalin, Matt said, "We’re the sole contributor to the CAD portion of the project, however we've been constantly working with feedback from people as received through email, GitHub, and in person from my coworkers.

"Having four mechanical engineers as coworkers who I can toss ideas off of has probably been the biggest reason for the success of this project," he says.
