I created this mount as the other mounts i found for 4020 blower fans all had issuues in terms of lining up the flow of the air to beneath the nozzle at the same time as ensuring that it doesnt scrape on the print.
By angling the fan away from the nozzle it allows a straighter path through the duct to the part at the same time as ensuring space for airflow for te hemera heatsink.
The fan duct has been updated with a far superior design which blows air on both sides of the print and gives all round superior airflow.
Assembly:
The mount attaches to the hemera through 4 points with 6mm M3 countersunk screws and the fan attaches with a minimum of 2 points with M3 16mm non countersunk screws. The duct is attached to the blower fan using super glue.
Happy Printing!
Print the mount without supports. Orientate the mount with the sqaure side on the bed. Canbe printed in PLA but PETG it ideal for it s superior heat resistance. The duct only requires supports on the print bed only.
