I'm not sure if this is the right place to ask but I've been trying to find some different size control boxes for my projects. So far the only thing I've found is some 4x4 & 6x6 electrical junction boxes.Does anyone know of a good site where the boxes don't cost more than the whole project?
Check digikey, you will find thousands. I used cases from serpac.com, starting at $5 (also available at digikey).
Another option (and I’m biased, since I own my own printer), is to design your own boxes in something like Sketchup, and then have them 3d printed. Either find a friend, a local shop, or an online dealer like Shapeways (never used them, but theyre the biggest around I guess), and have them finesse the design and print it for you.
That way you can design in all the mounting points, openings, and what not as you see fit.
If you’re doing A LOT of projects, or projects that require special boxes, you might want to look into getting a printer of your own. Some smaller printer are now running <$500. It might save you money and stress in the long run.
Part of the fun of a project is the box. You can make them from wood or angle aluminium. I also use old blank PCBs for the sides sometimes. Laser cutting can be useful but a few hand tools will do a good job.
Then you can use ready built boxes not designed for electronics.
This project used an acrylic pencil holder turned upside down with a wooden base painted black. https://vimeo.com/125778390
if you are looking for a hinge cover metal enclouser, like a ritttal or Hoffman box, you need to spend a couple hundred dollars on sensors so the boxes do not seem so expensive.
Some great ideas, Thanks
Check out some of the other types of boxes I have made for projects here:- http://www.thebox.myzen.co.uk/Hardware/Projects.html
connection terminals and enclosures are big ticket items compared to most elecronics.
main stream sources offer long term planning for products. if you are planning on a long term product, go that way.
if you are looking for a one off, then the after market source offer overstock or discontinued parts for good prices. e-bay is a definite source as well.

Having never priced these, I'm assuming it's cheaper to buy a welder, learn to use, and fabricate your own?

not sure, if you have a brake to cut and bend, and can powder coat, you can save the $$$$ if you need a lot.
8"x8"x4"nhinge cover, about $50, plus shipping
Since I work in basically a titanium sheet fabrication shop, I think I'll make my own.
