SummaryIts a shroud to hold a 40mm fan that will clear a 60mm angel eye LED attached to the mount I also created. Added a file with support on the bridge for the wire clearance 6/6/15 v1 works fine for the supplied rostock max v2 hot end. *v2 and v3 were removed because they had horrible air flow. Working on another model now for an ultra low profile fan with more air flow. InstructionsI used ABS @ 1:1 ratio; PLA should work fine for this application. I printed it as a shell on the first version and 20% infill on v2. Align the pocket for the fan against the table. Raft will help since this part is only .050" (1.25mm) on the print bed contact. Attach it to the platform using a 4-40 or m3 screw.
