The file 'Laser Enclosure Vent Adapters 4″ 3D Printer Model' is (stl) file type, size is 327.4KB.
These are adapters to install a 4-inch inline exhaust fan to a DIY laser engraver enclosure. One of them goes from the enclosure to the exhaust fan and the other sits in the grove of a vinyl window. These are for 4" dryer ducting.
I printed using PLA+ but I would think regular PLA would be fine. Each took 3-4 hours to print at 80mm/sec. @ .28mm layer height
