Hive Guardian Nerf Shield

I've always loved the shield mod that came with the [ECS-18 Stampede](https://nerf.fandom.com/wiki/Stampede_ECS), but it doesn't fit on every blaster because of the narrow slot on the bottom. So, I've designed a slightly different take on it, with a barrel mount instead. That's not perfect either, of course, but it's a little farther forward and helps keep the shield out of your way.
