This board is a part of the 3D printed version of the miniMO modular synthesizer, an open source and open hardware project also hosted on Github.

The board has 15 terminal strips and a rail on each side. I designed it because I couldn't find any commercial models of this size with side rails.

To print the board, use a small (0.25mm) nozzle, and print it upside down, that is, with the grid against the printing surface. The metal clips should fit in place without much trouble; they might protrude a little bit at the bottom but in my experience that's never been a problem.

I have used several of these boards in the various versions of the synthesizer since 2014 (see above), and the circuits I've assembled on them have always held fine, even after transoceanic flights.

The 3D model was designed with wings3D.
