Fan guards

I replaced my extruder and bed fan and just opted to not put the fan guards back on. I can now print any filament I have at at least 100 mms. For my setup petg used to be 50 mms. I think the increased airflow helps keep heat from creeping up the filament. I was seeing a lot of jams where the filament doubled over itself. PetG at that speed is awesome !!!

Huh! (I wonder if I can keep from sticking something in there?)

The best time to make "Fan Modifications" is midway through a 12 hour print btw. it's been proven by science.

On a side note the fans are not as loud either.

I replaced most of my fan guards with wire-metal ones, and all of my bed fans are guardless. I break fans just as frequently (and the filament drive fans always fail from bearings, not carelessness). Maybe that's why I've been successfully printing at 100-120mm/sec?

I think you are right. I'm going to try to push it to ight and see.

Recommendations for wire fan guards?

What fans are you guys replacing them with?
If the CFM is at least the same as the stock fans and they are quieter, that seems like a win all around.

I just bought a bunch of 40mm wire guards off of Amazon, they were more or less sold by the pound.
I've got like 2 dozen ... how many do you want? :p
