This is the newest generation of the Leon me cooling. Updated fun ducts provide cleaner airflow to the nozzle providing much better cooling than the previous versions. If you need to mount a v6 hotend check out https://www.thingiverse.com/thing:4771270 this design will work with the ender 5 family, and the older cr10 family, and the older ender 3 family. and any other printer using the the oldish creality shroud Things you will need: Either us #6-32 by 3/4 or 1/2 inch bolts, plus #6-32 nuts, or metric m3.5 by 20ish mm bolts, with the respective nuts, this was designed around imperial bolts to mount the fan ducts, but it should fit m3.5 the 4 m3 screws securing the heartbreak fan from the original shroud, and then either 1 or two 5015 fans. Whats included, a standalone bltouch mount (x offset is -26.5, y offset is -17.775 mm), a fan duct with out bltouch mount(x offset is -35.12, y offset is -23.665), and another fan duct with a bltouch mount in addition to the base. Install instructions, print the base out of something you trust with the temperatures you are going to be printing at, same goes for the fan-ducts(for the fan ducts i recommend printing them upside down and to use a brim), i printed mine out of petg. once down, seed the bolts into the holes and watch out for cracks, the tolerances are tight and might need some force to get it in there, then take off your hot end assembly completely, and mount the base using the original screws, once done remount the hot end and do a quick test fit to make sure the bolts you are using don't push against the hot end, you will want to add nuts to the bolts before mount if this is the case, and attach the ducts. you'll want the ducts bottom to be about 3-4 mm above the nozzle, and put in the fans(the fans are friction mounted) and hold your finger under the nozzle to make sure your happy with the airflow. after that happy printing.
