Not a ton to say about this one. It's an adapter for if you do not own/use ryobi tools but want to use my recent blasters which use ryobi tool packs. It's just an empty case in three different sizes for holding batteries on the ryboi connector. Not (yet) tested with actual ryobi tools.

I've included stp of the packs and the pack adapter I use, and stl's of the packs. Currently does NOT make your lipo/etc. work with the regular ryobi adapter, you'd have to wire an xt60 or whatever connector instead of using the ryobi tabs, but it would not be especially hard to make it work with the adapter for just power.
