Here's the animated file with directions. If you have problems, let us know.
Note that the custom doors may look misaligned when you place them on a map but they should look normal ingame. That's because the person who made x2mdl (the animated model converter tool) set the 'default pose' be with all the model parts scrunched to XYZ=0 instead of in their actual positions.
On a related note, I just realized x2mdl shrinks models a little when they're converted. It shouldn't matter for enemies and such, but something like a hidden door that has to be a precise size will be very hard to pull off.
