Hackaday Prize Entry: 3D Printed Modular Keyboard

There is a big community of people creating all kinds of synthesizers, but until now no one has attempted to make a keyboard controller like the one [Tim] created. Not only has he created the keyboard synthesizer, but he’s developed one that is modular and 3D printed so you can just expand on the synth you have rather than go out and buy or build a new one.

The design has a lot useful features. Since the design is modular, you can 3D print extra octaves of keys if you need, and simply build off of the existing keyboard. The interior has mounts that allow circuit boards to be screwed down, and the exterior has plenty of available places to put knobs or sliders. Anything that could possibly be built into a synthesizer is possible with this system, and if you decide you want to start small, that’s possible too!

All of the design files are available from Pinshape if you want to get started. The great thing about this controller is that you could use a 555-based synth in this keyboard controller, or a SID synth, or any other synth you could think of!
