NOTE!! I forgot to make room for PINDA. Working on a new version now!
I could not find a suitable fan shroud for the E3D Volcano hotend so i created one. I took the original design by Josef Prusa and attached an ring to it to create a nice airflow all around the nozzle for proper cooling while printing in high output. I tested it and it and it fits and works perfectly. I kept the Original Prusa look just because it looks super cool and to show my respect to the creator Josef Prusa.
Print at 100% infill and lower the speed of the printer a bit because all walls are kinda thin and you don't want any holes in the shroud to keep the airflow as good as possible. Use supports but only from buildplate.
