Wanted to remind people of a cool use of these that popped up for me recently: if you do not have adapters for your vacuum/air systems or need an adapter to connect the hoses to your tools, just print them.
Edit: Also throat plates

Aside from the dewalt, I do not have these, although that wen rotary tool item I may want to adapt for my rotary tool, because that could be nice when I don’t want to use the add on with it giving a length between the tool and a pencil type holder for the bit.
