makita battery adaptor heavy duty

I started from joeynovak's work...
I transformed it "heavy duty" version to fit on ANY 18 volts tool.
With this, you can turn any DeWalt, porter cable, ryobi, bosh, etc 18V tool to work with your makita batteries.
For myself I transformed a 34$ porter cable jig saw to work with my makita batteries... Makita jig saw is like 150$!!
And more recently, a ryobi 18ga brad nailer: makita don't even sell any!
