fume extractor lid 6x6 ko-one

i was rather frustrated to find that the fume extractor form my laser engraver had a 6x6 filter but the lid was so close to the filters that it really only used the diameter of the hose and plugged almost immediately. i searched around looking for a taller lid that would allow the entire filter to draw air and couldnt find anything so i threw this together. i was designed directly off of the small 6x6 ko-one fume extractor. print upside down for minimal supports - only for the latches. i scaled my print down vertically only to 75% to reduce print time
