This piezo pickup was inspired by my first ever 3D printed design: a guitar pickup that was designed to hold an old “oyster” style pickup.  I wanted to make one that was more general and could hold a standard sized piezeo speaker. It is built for the  4″ (103mm) diameter sound hole on my Yamaha. If you are interested in modifying for a different size, I designed it with Autodesk Fusion 360 and made the design public.
