Festool Tracksaw to ShopVac 2-1/2" Adapter

I suggest printing the part in PETG, which is what I did.  I believe PLA would be too shock-sensitive for a vacuum hose that gets dropped and knocked around.  I printed with 0.3mm layers except where the notches are on the Festool end, where I used 0.2mm layers.  Let me know what you think, I always appreciate feedback.

I used “Super7”'s STL file as a basis.  I recreated the model as closely as I could, but the geometry won't be exact.  The Festool end has a nice lock on the tool.  The ShopVac end is tight.  I've used the same license as “Super7”
