Prusa Nozzle Fan Redirect (stop warping prints)

thingiverse

This is scaled to push fit into the Prusa nozzle fan. The original one snapped off during printing due to upwards warpage of a heavily overhanging section. (due to inefficient airflow to the nozzle of the original Prusa design) Not to worry tho as this one is an improvement on toyotaboy02's model of which i i took the shortcut of using the tried and tested interfacing part that i know fits the inside of the nozzle fan. when i pushed mine in i heard a crack so have uploaded i slightly slimmer fit model also. alternately you can scale up and down as required To follow up:- The print quality on over hanging parts especially on the right hand side has improved dramatically, i realise that the far side of the vent actually throws air backwards and probably past the nozzle so will probably improve this in the future but is night and day quality wise already so unless i get further problems this will suffice on my printer. (edit i couldn't let it rest so finished the modifications to allow the airflow around the side more efficiently, untested as yet but will definitely work better than the version i'm currently running as even a tiny airflow will divert a larger one) hope this helps as many people as possible!
