Piezo Earphone

thingiverse

This is so you can use a piezo speaker with a crystal set. As you need a high impedance speaker to hear the low signal of a crystal radio. There are 2 body styles.. I prefer style 1.1 Need to convert to cm. exported in mm... Do not need supports This was exported in mm....So scale will need to be adjusted accordingly. (X10) Cura doesnt read inches.
