Davinci Layer Fan 40mm

I noticed the air outtake was a little small and directed in 1 specific spot. I made the mouth bigger to allow for more air movement. As is said in the original, you can use a glue gun for assembly and to hold it onto the extruder housing. I added a fan filter on top as well because the fan gets really dusty. I just hacked away at the inside to make it bigger. Thats why it looks like a dogs breakfast. Works well anyway.
