This is my minifigure-scale Hulkbuster based on the mk44 from Age of Ultron. It has fully articulated arms, legs and hands; and can fit a minifigure inside since it’s built around the Nexo Knights mech piece. It can open up fully, and is around the same height as the Hulk, like in the film.
Instructions for this can now be purchased HERE.
