What about this for sling housing?

While wandering about a local carboot with the gf bored to death at 4.30am on a rainy morning I came across this for a mighty £1.50.

They are basically meant for screws etc but fit the bill nicely, small versions of some my large enclosures, they are roughly 75x50x50mm.

Should be good for little ones that are outgrowing there sling pots.

I've been using RUBs for years, can't beat it for so many reasons I've listed in the past.

RUB's are great, it's what I almost exclusively use.

Be careful when using them for slings, I've had a couple of escapes. Ensure that there isn't a large gap between the lid and the box itself, that seems to be a fairly common manufacturing error. I use these for young juveniles, but slings all get condiment/deli cups.

I've looked at them but the maximum gap I can see around the edge must be 0.25mm, they are quite tight fitting so should be fine
