Craftbot+ fan shroud

Craftbot+ Fans were different than the original craftbot. This shroud is a very tight design to force the fan air within a 8mm circle around the tip of the printer head with a 1.5mm gap from the printer head itself.

I printed these shrouds with a HTPLA Carbon Fiber from Proto-Pasta and then heat treated them in the over for an hour at 170 degrees F. A high temp tolerant material is likely needed.
