Akro-Bin 30210 Divider

I've got a lot of Akro-Bin 30210 storage bins that i use when printing parts for a bigger build that's going to be printed over time. Parts A goes in one bin, parts B in another etc. It's a great way of keeping track of whats been printed and whats left but when the printed parts is both few and small it's somewhat a waste of space so i printed a divider. Sure, i could buy one but that's not why we got our self a printer, right? Hint 1: If the bin has a dark color, print the divider in a lighter/brighter color - not because it's beautiful but because it makes it easier to see whats in the bin.
