Here I proudly present Batman's grenade launcher as used in the new movie Batman vs Superman. Modeled to be as accurate and detailed as possible, this replica gun even features a movable barrel to which you can "reload" with the included grenade round.
This gun was definitely a challenge to do and took around 50+ hours to complete, but I think it turned out quite nice. I also designed it to minimize the amount of support material needed as well as building "internal" joints to lower the amount of pins required for this gun.
I have included pictures showing how to assemble certain areas and I made a quick little animation showing how the barrel mechanism works. Assembly shouldn't be too hard; just look at the pictures for reference and you should be fine.
