30mm fan blades.

Replacement blade for 30mm extruder fan.

I had a broken blade on my extruder fan, it is an 30mm fan, so I designed this replacement with 8 blades. 

To install ensure to remove all remaining blades, and that the soft is free from debris, then just slide the replacement in the fan shaft. Be careful to not put too much pressure to the fan shaft as it can break the pillar support behind the fan.

I also have an inverted blades version if you want to turn the fan position.

Print it in ABS for a better heat resistance. 

Recommend to print with raft and with fan on, with the fan on the blades will be straight.
