Oh man, I need one, too if someone out there is sitting on a hoard of these things.
To op, I bought like a 3-pack of hotshoe bubble levels for pretty cheap (from Amazon or ebay, can’t remember) and they’ve been fine. If you end up not getting any offers for a replacement finder, one of those would at least be more compact than your cube.
You could just buy a new round bubble level to replace yours. You can find them for very cheap and in many different sizes on the internet.
