Makita battery charge adapter for 7.2V, 9.6V, and 14.4V

I have several older Makita tools that came with Ni-Cd batteries. My newest (about 15 years old) came with Ni-MH and a charger to match. When the Ni-Cd batteries died, I replaced with Ni-MH and used the newer charger. Sometimes that charger isn't near and I wanted to use my general purpose charger instead. I designed this simple adapter to allow for easy attachment.

Step file works fine. Metric Fusion model included. Be kind, as I'm new at that.
