    Bottom face>>Sketch.
    

    

14. Step 14:

    Convert the outer edge.
    

    

15. Step 15:

    Under curves select Helix and spiral.
    

    

16. Step 16:

    Defined by Pitch and Revolution at pitch=3mm and revolution be 13~14.
    

    

17. Step 17:

    Front plane>>Sketch.
    

    

18. Step 18:

    Draw a square of 2mm side.
    

    

19. Step 19:

    Exit the sketch and then sweep cut.
    

    

20. Step 20:

    Select the box as the profile and the helix as the path.
