This is a fan shroud upgrade for the Elegoo Neptune 2x family of printers (it might work for other i3 based printers like Ender3 etc. but this is not tested). For the upgrade you will need 2x 5015 24V blower fans, a BL-touch, a M3 tap and some M4 x 30 bolts and  M4 nuts. All other hardware is reused.To install: Remove old shroud, remove hot-end fan from old shroud and cut the part cooling fan wire (do this while printer is off). Tap the holes of the BL-touch with a M3 tap and install the BL-touch using the screws provided with the kit. Then install shroud while not fully tightening the adjustment screws. Lower the nozzle to the bed and adjust fan ducts to be ~2mm from the bed and equally far from the nozzle.Tighten the adjustment screwsSolder the blower fan wires to the wires previously cut (NB! mind the polarity)Install blower fans in holes with the impeller facing outwardsAdd M4 bolts and nutsEnjoy!Print orientation is shown on the picture also use paint-on-supports as shown on the image.The offset for the probe is x=0 y=-25.
