    @Axel_Kollmenter is right, @Evan_Reese could totally do this. But perhaps not at 6:30 in the morning?  :D

    @max_mistarz, here is one approach you could start with. Keep in mind a split part or face feature usually works fine, but in this case it did not; so I used Thicken and Boolean subtract as a work around.
    Link to example document
    • Sketch the main shape.
    • Revolve the main shape as a surface.
    • Split the main surface with a helical surface.
    • Create a profile sketch normal to the end of the new curve along the face of the main shape.
    • Sweep the profile along the curve.

    Haha sorry. I´m from Germany, here it was 10am ^^

    Your solution is great! But how did you do the squeeze in the helix? I checked the document you linked to your comment but I dont understand how.

    EDIT: ok I think I got it but its a bit too complicated for me right now. I couldn´t have this done alone yet.
