Heavy Duty Layer Fan duct for 50 mm fan, designed for FLASHFORGE Creator X, but it should fit similar models - ONLY tested on the FLASHFORGE !
Good air flow - No flimsy parts !
You will need 2 pcs M3 x 55 mm screws for mounting !
If you can't get 55 mm, cut a 60 mm to length ;)
I had some issues when slicing in makerware. It created the bridging over the outlet in the wrong direction unless I rotated the object 45 degrees ! Check in preview :)
