Well there is:
Glaves converted meshes (There are also links on his thread that lead to other good items so check those out)
https://feral-heart.com/smf/index.php?topic=11142.0Two years ago, I could hardly find a thing to put in a lab map I was making, So I created a few (Super basic) objects for me to use. If you don't mind odd-looking and possibly non-fitting objects, Just ask and I'll put them up. And sorry, no screenshots of my objects are available, It's just plain old shackles and food/water bowls(Food and water already in the bowl), Each of which I had put together in a couple seconds.
If I find anything else that will fit the lab theme I'll put it here
