Can 3D printed instruments sound good enough for music?

That's the fundamental question the immensely talented Super Valid Designs asks in a recent video on YouTube. The answer – an emphatic near four-minute long song – uses over a dozen fully 3D printed musical instruments with zero digital effects or post-processing. This video gives a peek behind the curtain at the process, but the main show starts at 21m 40s. Alternatively, you can listen to it on popular music streaming platforms, too.

Some of the instrument files are available on their Printables profile, should you feel inspired.

Keys and CAD
Keychron just released what appears to be all of its design files on GitHub.

Best known for its smart-looking mechanical keyboards, the brand's in-depth GitHub repo includes all the CAD for some 80+ products, giving you access to reference files to adapt, remix, and design around. The kicker? Personal use only – this is source available, not open source. It gives a fascinating look behind the curtain at a series of minimal looking peripherals, and for owners, an easier starting point to design your own 3D printable accessories.
