Ultimaker 2 Fan Shroud

I've been modifying the Spirit fan mount, which can be found here: https://www.youmagine.com/designs/ultimaker-2-fan-mount--2#!design-information. I'm working on making it compatible with Anders heater block and I really like this design because it's enclosed, preventing temperature errors caused by open bottom designs. To make it work, I've lowered the whole thing by 8mm, which means the bottom of Anders' heater block is only 4-4.5mm away from the fan shroud enclosure. As a result, I didn't need to use any tape like Sprint's original design suggested. So far, I've used ABS for the shroud and had no deformation at all (check out the red shroud above) after two weeks of testing. I'm now running an XT-CF20 shroud with no issues whatsoever, both at 250 degrees temperature. However, I haven't tried using PLA for the shroud yet. In addition to these modifications, I've also enlarged the nozzle hole to accommodate the socket supplied with Anders' nozzle, making it easier to change nozzles.
