This is a fan shroud that is designed to provide a vortex style cooling stream around the hot end of an AnyCubic Delta (pulley, Linear, or Linear-Plus).

...Show more it in a temperature resistant material. I printed V2 in PLA and it worked very well until I stopped a print very close to my heated print bed and without cooling air running thru the duct it overheated and deformed.
It is similar to the design by juhyukhong but I changed the cooling exits to a vortex style. I also added a open sided version to provide a view of the hot end.
EDIT: I added 2 additional versions with added support in case you are using PLA to try to reduce the deforming issue I had on my first test on the V2. Since the AnyCubic does not have an insulated Hot End you would still be advised to use a temperature resistant material.
EDIT 2: I removed the supported versions as they had interference issues and did not help with PLA.
EDIT 3: I corrected the extra support versions to eliminate the interference. Please note that I do not believe this will work long term if you print it in PLA.
