Geeetech A20 optimized fan duct NEW
thingiverse
This is a optimized version of the fan duct for the stock A20 fan, maybe it is suitable for the other Geeetech printers (A10, A20M, A30), if you try it let me know. It is more aerodynamic, avoids any internal turbolence and better directs the airflow towards the nozzle. It is plug and play, you won't need extra bolts *UPDATES* - external design - changed the angle of the airflow - reinforced the support - it has more clearance from the nozzle height (it sits higher) old version: https://www.thingiverse.com/thing:4975741
