easy removable and easy to clean filter for 92mm fan

This is an easy removable and easy to clean dustfilter for a 92mm fan

1. you can glue an nylon filter to the inner frame 
2. you can pause the print (at layer 9 or so) an lay a nylon filtermat on the print and resume the print.

I used the second option, I found ist easier and faster.

print with 0.3mm layerheight

You only need 4 screws to attach the outer frame to the fan. Then you can slide the innner frame with filter in it.
