Scotts Brand Yard Tool using DeWalt or Hercules 20V Battery

I got a hedge trimmer and battery at a thrift store for $15. No charger. A charger and spare battery cost about $70 (used). These adapters allow me to use a Dewalt or Harbor Freight's Hercules battery. I made this in two halves so I will be able to adapt other brand of tools. For hardware I used 16GA wire, M4 x 25 button head screw, M4 x 16 countersunk screw, four M4 x 8 button head screw, two M4 nuts, and 1MM x 6MM brass strip from Amazon. The two longer screws are actually too long, and I had to sand off about 2MM of length.

Assembly is fairly simple since both sides use male connectors. The brass fits tightly in the slots. Get the brass slid in longer than needed and slide assembly onto tool or battery. That sets the distance to fully engage the contacts. Mark the brass 1 or 2mm in from the back side, remove and cut to length. Do this for both halves. I put a bevel on both sides of the brass, contact side, for better insertion into battery and tool. Solder wire at the end of the brass and insert back in the slots. Wrap wire inside the channel to get the wire length to cut. Remove and solder wire to the other brass contacts as pictured. Insert brass back into slots and slide adapter fully onto tool or battery push brass in until it is seated. The ends of the brass should slightly inset in the back cavity. Hot glue around the brass up to the surface. Add cover plate with the four screws.

For the PLA I used generic black, green and blue and Deeplee Sunflower Yellow from Amazon that is the closest I found to the DeWalt yellow. 0.20 layer, 3 to 4 walls, 25% infill. I did use tree supports but I think everything can bridge without it. It worked during prototype. Since it took me about 2-1/2 to 3 hours to print each half I did not chance it without supports. I printed on a SparkX I7.
