Anet A6 Magnetic Extruder Fan

I remixed this (https://www.thingiverse.com/thing:2287009) because I had trouble sourcing the screws needed and I wanted the option to add a filter to stop debris being blown into the extruder.

6 x 4mmx4mmx2mm square or 4mmx2mm round magnets (or 8 if you want to glue them to the hex screws)
4 x 2mmx10mm flange head screws
2 x M3x25mm hex screws
1 x 40mmx40mmx2mm fan filter (optional)

Update 2 - Added options for both
