these are the 3.5mm jacks commonly used for DIY synths. there’s a part attached in this topic for the older version PJ301M-12, but the breadboard view isn’t actually correct, the spacing of the legs is off, and it’s difficult to use because it’s a side view. i used that file as a starting point; my version is drawn top-down, with correct spacing for the legs:
