Wanhao Duplicator i3 Factory 30-40mm Fan Adapter

Offset 40mm fan adapter for use with the factory metal fan duct. Requires 2 short M3 screws and 2 longer ones. I had extra short ones from removing the frame screws for my light mounts. The long ones just depend on how deep your 40mm fan is. Mine is very deep so I used 20mm, but 10-15mm would probably do it for most.
