Open vambrace

Originally I was going to create a mechanism to open the vambrace but 1: I'm lazy and 2: I had no idea how to do that if you know how to do it or know I site I can learn from the please send a link.

The hinges aren't bolted on or glued as one might think, they're actually held in place by compression. They slot between the vambrace framework and armor so tightly that once the bolts were fully tightened for the framework there is no way that the hinges are coming out
