Hey Tamer, just be carefull when you put the keys in the base, they are a very tight fit and if you are not carefull (as I was not) you might break the little tabs that fit in. They are not seen so its no problem but just wanted to make you aware that the transparent material is not as strong as the other two. If you are going to paint the base with primer or gray color do that first then assemble... all pieces should have a tight fit but once you are ready use some superglue to ensure they stay there.
