    Making a replica of Mr.Krab using a positive "mold" (mini size model)

    Hi.
    This is my way to get hands on "H&M Mr.Krab(hydro 3)"
    My model is 450mm long.
    Pictures will speak for themselves.

    The fist thing was to get as much pictures of original that I can find on the internet.
    This one is my favorite:


    Next step was to draw the plan in avtoCAD (2D).


    Then I cuted the parts for positive model on a laser CNC:
