I tried to separate the shield into several parts and while doing so discovered that the shield is hollow and I can not figure out how to make it solid. Is there any way you could release a solid version or comment some advice on how to make the shield solid? I could try to revolve a disk inside the shield but doing so would more than likely screw up the back side of it.
I tried to make it solid in Meshmixer, but had trouble and don't know where to begin in Fusion 360. Any help would be much appreciated!
