Summary

In order to have good PLA print, you need to cool it as quick as you can from all sides. With Rostock Max V2 effector, you can put up to 3 blower fans for PLA cooling. However, you only get one blower fan in the kit. To cool from all sides, you will need to buy 2 more blower fans. This means you have to spit more wires to feed the other 2. To avoid all that, I designed a new blower fan unit that can direct air from the blower to all 3 sides. You will need 3 small screws and some crazy glue to put together 3 printed pieces. See images on how they are glued together and how to mount it. You can print the whole thing with no supports.
