This is a mount for a cordless rechargeable heat gun. This holds both the heat gun itself, as well as the deflector.

The hole is sized to a 6MM bolt, as that is what I was mounting mine to.

I also have a different version that fits the Honeycomb Storage Wall! - Check out my profile to find it.

There are multiple brands online that sell this style heat gun. Any of them should fit that have the same profile.

Here's a couple of links to the ones I have purchased:
