Gridfinity Bin with Transparent Lid, 1x1, 3U - 6U

I was looking for a storage solution for many small parts, screws, springs, o-rings, connectors etc.I also needed a solution with a lid that latches and also shows me the contents just by looking. So I came up with a lid with a piece of packaging plastic, cut out to size with plain scissors and the cutting template that's also included. The bins are size 1x1, but vary in height from 3U to 6U in half steps. There are colored versions with color markings, as well as single-color
