Air Assist Tube for Laser Diode

thingiverse

This is an air assist tube for a diode laser. I designed it for my ortur laser master 2 15W laser. But it should fit most common lasers. The inlet is 8mm with a taper. You can simply push in a 8mm OD hose or use a 1/8" NPT tap and a festo fitting will work as shown in the pictures. For Air supply I used an air compressor with a flow regulator. But anything such as a fishtank pump will probably work. The laser shoots through the middle and the air supply creates a vortex around the laser which keeps smoke from blocking the beam and reducing the power. It also keeps the parts cleaner. The mounting points are seperated by 43mm and 5mm.
