Bolt Locked Modular Shelves - Corners?

Has anyone made anything like this? I am looking to make an inside 90 degree corner that is 8 deep. Dosn’t need to hold a lot of weight, in this case, the corner is more decorative. The regular straight sections would hold the weight.

Any ideas or insights of issues a newb like myself might encounter while trying to make my own is appreciated also.

Thanks everyone
