Fume extractor funnels

while laser engraving i found that the hose didnt draw all the fumes, after thinking for a bit i realized since fumes rise, the best way to solve this instead of drawing across the part would be to draw all air down and then into the extractor. i have put together a couple a air funnels so far and greatly reduced the amount of fumes/laser debris escaping. These also have a 2 fold benefit of acting as a laser shield since they are solid walls i am not getting blasted by laser reflection in my work area.

the square one is 60mm and the round is 70mm at the base, they both have 47mm output ports on them to allow a 50mm extractor hose to slip on and have freedom so if the hose is too stiff it still allows placement where/how you want around your piece. the square also has an additional riser that can be added on top to help gather/direct more air as i noticed the original still had some dust/debris rising out.

the primary funnels are printed with supports for the hose connection but tha
