This will print for E2. Print mirror image for E1. To complete, You will need: 20mm pcb hex standoffs @3 Misc 3mm screws 1.5mm (cant remember exactly, I'll edit later) screws (amazon computer screw assortment) 32mm led ring 53 mm fan and 40 mm fan (see below) This uses the pre-existing bolt holes for the metal shroud and the bolt holes that mount the back plate to the gantry trolley. To mount the fan plate to existing backing plate: 1) Reuse the screws for the metal shroud, inserting through the back per usual. B) Remove the plate mounting bolts. Substitute the standoffs for the top two bolts and bottom rights. Third, bolt the Fang to the top two standoffs. Line up the bottom but do not bolt until the 40mm fan cup is added. Lastly, attach the 40mm fan shroud to the backplate standoff by lining up and inserting a bolt through the fang mount on the bottom right. The install the two computer screws on the left of the shroud.- CAREFUL, those screws strip easily. You may want to drill the holes on the duct slightly over. The screws will self tap the threads in the backing plate, but don't strip the head. The tolerances are pretty tight as I usually hand machine things (reamers, etc.). So you may need to enlarge some of the holes. It all prints fine. However, I ended up with a lot of artifacts on the Fang part. Surface finish is terrible. Pretty sure they are artifacts from whoever smoothed it, as the supports print flawlessly. It may be my slicer or printer. You may want to reshape the Fang tips to better place the flow. The LED ring is from amazon. It cam in a pack of 5 but two had corrosion on them and one was missing solder pads. I had purchased one from a different supply that was identical except it was missing the predrilled mounting holes. MAKE SURE you get the ones with holes. PCBs are hard on normal HSS bits. I tried to look for an amazon reference # but the listing has change to strip lights, so not sure what's up with that. Don't buy off brand junk fans from amazon.
