Don't you hate that most wood working tools have random openings for the vacuum port? Worse, the vacuum tubes are also non-standard. This will allow you to print an adapter to accomodate most vacuum hoses into most vacuum ports of your tools. It even allows to have the adapter to either slip over the tool port or inside of it.

You'll have to open FreeCAD and change the parameters on the spreadsheet to match your needs. You can even put the tool's name that it is intended for.
