Printing:
+ I printed mine at 0.3mm layer height with 15% infill at 60mm/s. The shroud was printed with supports disabled and the rest of the pieces with supports(one of the brackets needs supports for a couple of inset screw holes).
+ I printed in eSUN PLA+, but regular PLA should do the job just fine as well.
Assembling:
+ Be careful when sliding the blower brackets into place as applying excessive force may cause them to break. Learned that the hard way.
+ Once the 5015 fan is installed, the brackets feel pretty sturdy thanks to the rigidity provided by the body of the fan.
+ You can superglue the 5015 fan brackets if you want, but It's not necessary. I didn't glue mine and it holds up just fine.
+ As far as fasteners go, I used machine screws and just pre-tap the holes with one of the screws before mounting the fans.
Hardware:
+ Original shroud screws(x2)
+ x4 M3x12 screws or other self-tapping screws that fit the mounting holes for the 40mm fan.
+ x2 M3x20 screw to mount the 5015 blower fan.
+ x1 M3x8 screw for mounting hole where BL-touch mount overlaps Fang mounting leg.
Fans:
+ I'd previously converted all my fans to 12V fans using a step-down regulator to power them.
+ x1 40mm fan for hotend ( stock one may be used, but I went with a Noctua NF-A4x10 FLX)
+ x1 5015 blower fan (I got mine from Amazon: https://www.amazon.com/gp/product/B071WMHNG5/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1)
Testing:
+ I printed the 150mm bridging test found here: https://www.thingiverse.com/thing:2754688
+ It did well in my opinion. Not perfect, but you can judge from the picture.
The Bad:
+ If you have the frame brace mod on your Tornado, you will loose some height because of the blower fan sticking up.
