we are constructing a brand new fan cage with 2 additional cooling fan. The cooling fan cage is a major issue. Some materials don't like too much cold air however with the V2 hot end they need to run on 100%.
I'm so sorry that we don't share such kind of file to public. As I known, there has other users have designed similar kinds of things, you can search on the forum or on our STL sharing website. Here is a link for your reference: https://www.thingiverse.com/thing:2207389.
