Though there are plenty of these adapters out there, I wanted to design one that printed with no supports as two pieces. The two piece design allows for the maker to use two crimp style spades that can be attached to wires and sandwiched between the two halves. I've been using these to upgrade my kids ride on toys. The adapter is held together with some basic m3 hardware and nuts. Print and Enjoy!
