Dewalt 12V max/Milwaukee M12 into a 12v power source

I thought I would put this out there. Quick project for today after I put a new O2 sensor in the Tundra. I have been looking on Amazon at the 3D printed power adapters. I thought they would be handy to have to test trailer lights and other 12v projects. I'm a Dewalt 12V max fan and had a couple extra chargers around. I took this one and gutted it out, desolderd the prong board to only have the positive and negative. Soldered in a couple wires and its good to go. I used it today to test a couple of vintage Toyota digital clocks I need to sell.

For M12 batteries, you can take some male spade connectors and insert them directly in the positive and negative posts. Crimp the spade connectors onto some 16 gauge wire and terminate that with alligator clips, and you have a portable power source to power up lights and electric motors.
