Freestanding Pegboard Wall - using Multiboard/Multigrid?

I’m wanting to make this (actaully two of them), but instead of pegboard I want to use Multiboard/bin/grid. I’m hoping for advice on best practices. The Multiboard areas of each will be appx 950mm(w) x 1250mm(h) and 650mm(w) x 1250mm(h).

I’ve never printed anything Multibuild before. This will be my first foray into the system and I’m both super overwhelmed and super confused.

First, is there a dictionary?? I think that would be super helpful. Maybe it’s out there in documentation somewhere, but I haven’t come across it.

Should I use the square tiles or octogon tiles? What mount should I use? I’m thinking offset so I can use both pegboard accessories and Multiboard/bin accessories, but is that really neccessary? I could just do flushmount to a sheet of plywood behind the boards and utilize the hooks that fit into the octogon tiles, right? Oh, and I’d like the cleanest look possible without sacrificing strength.

The board won’t be holding much weight of individual items (craft room/sewing room), but still want sturdy and long lasting.

So…do I use square or octogon? What mounting do I use? When mounting, does each tile really need 4 screws??

Final question: the multiboard planner utilizes full boards (10×10 in my case) to the left and compensates to the right (the 650mm(w) has 10×10, 10×10, and 6×10 boards). Is there a way to have it center the tiles (i.e. 8×10, 10×10, 8×10)?
