The file 'K40 40w Laser Exhaust Fume Collector 100mm 3D Printer Model' is (3dm,stl) file type, size is 1.0 MB.
Fume extractor adapter for the popular 40w laser engraver. It uses the screws already on my machine, that were keeping the inner fume collector.
Diameter 100mm (about 4 inch)
Hope it helps.
