This is based on Lichtjaeger's awesome design. I wanted to make it a bit lighter and also use the Nut that comes with the revo to fasten it instead of the Prusa method. (Which I am not a big fan of) Insert the plastic Nut that comes with the Revo into the grove and then tighten it by turning the heatsink/nozzle portion from the bottom.
I started researching these because my Revo Micro was experiencing bad heat creep from using the tiny hotend fan it comes with and virtually no airflow across the heatsink. I've tested this design and I'm no longer experiencing heat creep related clogs so far so I am publishing it to possibly help others with this problem.
I printed the one in the photo using Prusa PC Blend Carbon fiber but PETG/ASA will work totally fine.
Happy Printing :)
