Laser Fan Nozzle

Fan Nozzle for 40W CO2 laser Basic Blue Box Chinese K40 type. Uses a standard 40mm fan to direct air into a stream to assist clearing the laser working area of smoke and particles. Made for my machine and tested on several jobs, working very well. Needs to have a high air-flow fan, I used a 40mm fan pulled from old rackmount server cases. EDIT (07-Oct-2019): Updated and uploaded improved model plus some in use pictures. Lock screw hole can be threaded for an M4 bolt to lock onto the laser head.
