osVAC M32 oval vacuum adapter for legacy Festool (Festo) sander

This is an osVAC adapter for older Festo (Festool) sanders with an oval dust connection port. To test the fit on your machine, you can first print the small calibration ring which has the same inner diameter as the part itself. Note that the calibration ring is slightly conical, so it will only fit one way around.

You can adjust a too big or too small fit in the slicer by adapting the Hole Horizontal Expansion setting. This size worked fine for me without any adjustments using an Ender 3 V2.
