I printed a Fang Replacement Fan shroud for my stock Tevo Tornado hot end. It's an improved version of my first Fang shroud, which used two 40mm fans. You can check out the original design here: https://www.thingiverse.com/thing:2756527 Printing Details: + I printed mine at 0.3mm layer height with 15% infill at 60mm/s. The shroud was printed without supports, while the rest of the pieces had supports enabled for a couple of inset screw holes. + I used eSUN PLA+, but regular PLA should work just fine as well. Assembly Tips: + Be careful when sliding the blower brackets into place, as excessive force may cause them to break. I learned that the hard way! + Once the 5015 fan is installed, the brackets feel 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. + For fasteners, I used machine screws and pre-tapped the holes with one screw before mounting the fans. Hardware List: + 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 Fan Details: + I previously converted all my fans to 12V using a step-down regulator to power them. + x1 40mm fan for hotend (I used a Noctua NF-A4x10 FLX, but the stock one may be used) + 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 Results: + I printed the 150mm bridging test found here: https://www.thingiverse.com/thing:2754688 + It did well in my opinion, although not perfect. You can judge from the picture. The Bad: + If you have the frame brace mod on your Tornado, you will lose some height due to the blower fan sticking up.
