The fan mounts to the shroud using #2 x 0.5" plastite screws. The shroud mounts to the ends of the M3 thumb screws using more #2 x 0.5" plastite screws as pinch bolts. Trimming some excess length off of the M3 thumb screws will result in a cleaner path for the air internally, but probably isn't necessary.

Hello! I've just printed this excellent design for a very old UMO. I know I need to rotate the heater block but due to the age of this printer want to make sure I don't break something. It looks like the heater wiring is threaded straight up through the head and doesn't look like it wants to bend. Those who have done this rotation, any techniques you care to share? Thanks!

Best fan shroud I have used so far. nhfoley is right about rotating your heater block. If you do it right there is still a mm or two of clearance between anything. So far it's working excellently.

Another thing people don't quite realize about this design, you can adjust it up or down as it's only held on by it's clamps onto the vertical rods. I like this as my last shroud (not this one) kept nicking any part of the print that decided to stick up.

It printed well and works well as well.
I added some copper tape as a heat shield.

A definite improvement over the original shroud
Original shroud on the left and Tapir shroud on the right. Main difference can be observed in the overhang on the left ear.
