If you’ve purchased the LEGO Marvel Super Heroes The Hulkbuster: Ultron Edition (76105), you may have noticed that it has somewhat limited articulation to it, especially with the knees. This is before LEGO mech builder Chubbybots came along and did some modifications to it to make it what it could’ve been in the first place. He doesn’t provide a parts list or instructions but he has released a video showing the techniques he used to give the Hulkbuster more movement in the joints as well as bulkier looking shoulders. Check out the video below and subscribe to his channel if you’re interested in more mech-type builds.
