Modified Adapter-Longmill Dust Boot v1

The dust collector adapter for the original LongMill wood-base dust boot was prone to be pulled out at an angle when using a shop vac with it. I downloaded the original design files in STEP format and added tabs in FreeCAD 0.20 so it could be screwed into the base.
There are 2 stl files: the original, and a 2nd one where I extended the top by 1".
The FreeCAD 0.20 files are included if you wish to make additional changes.

Use #6 1/2" machine screws to attach (these are short enough to not pierce the base). Machine screws have a flat underside to the head so they fit tight against the tabs.
I used a 7/64" drill for the pilot holes; do not use a power drill to put in the pilot holes. While there's a tab in the back, that may not be useful; I only fastened down the front 2 tabs.
