The file 'Sethi3D 5015 Blower Fan Duct 3D Printer Model' is (f3d,stl) file type, size is 368.4KB.
Simple blower for type 5015 fan for the Sethi3D AiP printer. You can download the fusion 365 file and adjust it for your printer.
I added double-sided rubber tape to the fan's contact points to reduce vibration.
