Erock had a cool looking homemade bracket in the back of a few of his videos with a long rail on the wall. Not sure if you're familiar with him, but hopefully he'll turn up and enlighten us.
It did look ridiculously simple and is possibly being used by loads of people already.
I hang mine from the hole, and I'm lucky I can hang the 3000, but it is touch and go, and I keep putting things in front of the bottom of it which stops me from swinging it out and no matter how many times I tell myself, I still do it. I'll be going down the wall hanger route once I move some storage out of the way on one of the walls in my workshop.
