Ender 3 Pro Hot End Vent Pannel

thingiverse

This pannel is used to block the air coming from the heat sink fan that can cause warping on the part being printed. It also acts as a ventilation diverter to better direct the air coming from the part-cooling fan to the filament being extruded. It is a direct fit on an Ender 3 Pro with no additional modification required using the original fan screws. V2 UPDATE : - Removed top of screw holes to facilitate the removal of the shield when changing nozzles. The screws do not have to be completely removed anymore. - Changed the angle of the air duct and changed hole for a slot to better direct the air from the fan to the part and extruded filament. - Removed the curved section below the fan that was on the original injection molded part. This facilitates the printing process as there is no support required. V3 UPDATE : - Screw holes were too weak with the top removed and would shear off. The top was re-added. - Removed sealing lip around heat block due to melting problems. - Redesigned air duct for a direct feed to the part.
