40mm Fan Dust Filter

thingiverse

Create a dust filter for your fan under the replicator to improve electronics cooling. This filter can be mounted on any 40mm fan for various applications. To install, move the fan flush against the inside and drill a 40mm hole on the side for intake. The filter's screw holes match a 40mm fan, and adding filters to intake fans reduces dust accumulation. Dimensions: 40mm x 40mm x 11.5mm. For assembly, print one of each part with settings of 0.20mm layer height, 13% infill, two shells, and 70mm/s extrusion speed. Cut and snap the material between frame parts, using a vacuum air filter or folded mosquito net as the filter. Place the frame insert over the material, secure it, then attach the housing onto the fan using existing screws or slightly longer M3 ones. To improve replicator electronics cooling further, carefully cut into the right wood panel, remove the bottom electronics cover, clean dust/hair, detach the fan, trace its diameter and mark upper screw locations, cut a 36mm hole for intake using a dremel, mount the filter housing on the outside and fan inside, reassemble, and place the filter frame with material in the housing. Note: this process requires caution as it involves cutting into the replicator's wood panel.
