Since we don’t have or can afford Festool/Fein, I understand that the port fits ShopVac hoses that have a 2 1/2" connections at one end to a smaller one at the other end. I can’t see one that has 35mm but there are some that go to 1.25in.
Personally I’m not a fan of the new item based on the specs but I have not tried it. My issues are that it was designed for a vacuum system that has unique sizing and not overly popular in North America and it attached to spindle.
I guess that you can’t hit a homerun everytime.
