Door sign (reworked)

I made a few modifications to the original design:

I split the main plate into 2 sections so that I could make one half red (stop) and the other half green (go).
I removed the curved sections from the slider. This way when the slider is covering one end, it is totally covered. I also widened it my 1mm to make it easy to slide (so it wouldn't bind).
I also reworked the end caps. They are not as deep and no longer have the points (guides?). They were not necessary. I did have to use my dremel to enlarge the circles slightly, but it makes an extremely tight fight now.
