Replicator Extruder Fan Guard
by garyacrowellsr, published
A couple of people on the forum have mentioned that they've broken blades on their Replicator extruder fans. Well, that sounds like a need for a fan guard.
I can't decide which one I like better, the radial, or the honeycomb pattern; so I uploaded both. To tell the truth, I'm not exactly thrilled with either, and I'm expecting someone to come up with a snazzier pattern.
The honeycomb pattern is probably more airflow restrictive, and it might benefit from a larger honeycomb pattern.
The honeycomb version had to be printed slow, with absolute levelosity to get a full grid pattern to print.
The radial pattern is easier.
Either will take a bit of cleanup to sharpen up the drool on the overhang for the clips.
It just slides down over the fans from the top, and it should fit snugly. Be sure that the bottom is all the way down against the carriage.
UPDATE 7/18/12: Some people had noted that adding the guard caused a high-pitched whine from the fans. The new files added (all of the *2 versions) move the guard out a bit from the fan blades. This should relieve some of the noise. (I never noticed it much since my Replicator is fully enclosed.)
