This is a .ZIP file that contains 3D model files. Two of the files are general 3D files (.IGS and .STEP), and the third file (.STL) is usually specific to 3D printing. The files can produce an adapter that goes from a 2.5″ dust collection hose, to the Dust Collector Step Down adapter, which is also available as a free download here.

These files can be used in conjunction with a 3D printer to produce the sort of vacuum line arrangement that I showed in my All in One Board Milling Station video.

If you haven’t seen that video, check it out here!
