Hitachi Dust Collection Adapter for M12V

I will have to modify this adapter in order to get more potential from it. I don't like having to make modifications to accessories that are poorly designed, but if I don't then it will never work right, and I can't have that! It's a pity so many tools are not given more thought about their maximum potential when they are in the concept stage of being developed. I seem to find myself always tweaking and changing tools to make them better, but a lot of what I do is simple stuff that should have been done at the factory before the product went to market.
