m18 to ryobi slide-on adapter

battery adapter for m18 batteries to the old ryobi slide-on style 18v batteries.
Ive included the fusion file if you need to modify it because I designed it to use the spades that came from an adapter you can buy on amazon https://amzn.eu/d/4ImTPJU for the newer ryobi style of batteries which I bought by mistake before realising these tools were the old style.
