Fan cable connector

There is a lot of dust in my house and the fans of my 3d printer keep dying. I need to replace them quite often. some people use connector for a quick swap, avoiding the need to open the printer electronics. But I live in a $#!7y country where these plugs are hard to come by. And I can't leave my home because of the pandemic. So I made a "warm" swap connector with whatever I had at hand. You only need 2 M3*5mm flat head. I also made a cap to avoid short circuit in case that the connector is near a metal piece or another connector. Q&A Q-You connected the red wire with the black wire. A-yes. the fans that I can get are wired backwards. and I prefer to swap the cables in the "warm" connector than open the 3d printer electronics and force the pins out of the plug. Q-How big are this connector? A-They are super tiny 13 x 6 x 10 mm Q-your prints looks like crap A-yes. the printer is set for strength not for looks. If you want pretty stuff take a look at my other designs.
