Plastic Header Pins

thingiverse

Print your own header pin plugs and then use leftover component leads or header pins (or paper clips if your desperate) to create your own plugs... OpenSCAD code included, but not for the faint of heart. Pin spacings should mate well with most breadboards/sockets/arduino/etc The three header pin version aligns pins with every second breadboard hole. The four pin version meets every hole, but is difficult to print.
