/diy/ - Do It Yourself

How do you guise mount stuff you've built?
I am building a couple machines that use arduinos. I I wanted a few different features and put them on separate small circuit boards so the whole thing would be modular, but I can't think of any really good way to mount the mess now.

The best I can imagine is below: a post will extend upward from the machine, and that will hold a piece of wood at an angle. Each circuit board will have threaded rod held into the top two corners, and then there will be holes drilled into the wood for the threaded rods. So each circuit board will just sort-of "hang" like that.

It doesn't need to be child-proof or look nice really, and I'd prefer cheap and quick. But I still want something that allows easy access to check wiring, and I can't find a lot that can do all that.
