It just needs maintance like the laser cutter does occasionally. I hadn't found the door to not be closing when I was in earlier in the week so it's just a different problem. For what it's worth, at least it opens a lot better than it used to. So that problem was fixed at least.
I'm sure someone at the space will tweak it a little again.

You'd probably be better with a couple of electromagnets or a shear magnet. Nothing to wear out then.
