a USB type A connecter made with 20 gauge solid wire for connecting to a USB port to draw power.
the hole is made larger than it should be because my printer cannot make a small hole without being a little poo head.
put 20 gauge solid wire in
use insulated wire and cut the insulation off
make the wire into a U shape and shove very hard into board
you should have 2 wire ends sticking out
cut one end with flush cutters that you got with your ender 3 or whatever (everyone has them)
bend the other end
