Hello All,
Does anyone know if there is a .stl file for an 'Airlock' style insert to allow locking a cage with the temporary plastic locking tags?
I did a search of the forum and didn't come across anything.

I figured this would be a fairly simple part to CAD up if I needed to, but wanted to check here first.

I found the pin ones with a slot have a flaw where you can slip the pin out with the tag still attached.

My first design had a hole all the way through, but that required drilling out the end of the cages I have.

I then came up with a two-piece design with a tag locking it together. It fits firmly over the lock area of the cage and doesn't fall off even without the tag. You can’t separate it enough to unlock the cage without breaking the tag or the plastic. It also has a nice flat area that the KH can write on.
