Propeller Style Fan Cover

thingiverse

This is a protective propeller styled hotend cooling fan cover designed specifically for the Prusa i3 MK3.\r\n\r\nIt safeguards users from accidentally inserting fingers or other hazardous objects into the printer's fan, while also guiding airflow directly onto the fan blades. The design takes inspiration from airplane propeller heads and features aircraft-styled warning labels.\r\n\r\nCrafted to be securely attached to the original Prusa i3 MK3 with a 40 mm Noctua fan, this cover uses push pins to mount directly onto the fan screws due to size constraints.\r\n\r\nUpdate 2018-08-03:\r\nA new STL file has been added that does not include a cutout for the threaded rod. Please note that using this version with a standard Noctua fan on an MK3 will cause it to crash into the Z threaded rod!\r\n\r\nUpdate 2019-01-06:\r\nAn additional version without text and cutout has been added, which is not suitable for use on a standard i3 MK3.
