Lol that was me! I still need to fix the lids, because I was in a little bit of a rush that night, atm each lid comes up and there is a little gap, so I cut a small rectangle out of the end of the original lid so it fits under the big bins lid, so I will now just ziptie them together - otherwise it won't be secure enough.
I'll post some pictures of it when I do them. Right now I'm holding them down with books
