Drop ceiling corner socks

Couldn't get the corners of my drop ceiling look good, so I made these. there are two types of corner, each with a "supported" and an "unsupported" version, which I called "empty".

By "outer corner", I mean the type that kind of goes around the corner of the wall, and the simple "corner" type is just your usual corner when the room is rectangular.

The supported version are available if your rails have a space between them. The support just slides between the rails in that case. if you have no space between the rails in the corner, use the "empty" version
