Type A is the first version created, utilizing friction of zipties to hold the fan in place. This type looks nicer when using zip ties because you won't see the head of the ziptie on the other end of the shroud. It might be possible to use screws with Type B or C, but it will be easier with those versions. Type B was added later and uses screws. This version may use a little less plastic than Type A, but might appear less symmetrical. Type C was created at the same time as Type B. The difference is that all holes are outlined in the same way, making it more symmetrical than Type B. It may require a bit more plastic than Type B. All types have supports on the lip that grabs onto the cooling ribs. They print easily and can be seen in the finished print picture, showing they're not excessive.
