Required Items; One of Neje Laser Modules A40640/A40630/N40630 1ea 50x50x15 5v Blower/Radial Fan 2ea DIN7985 3x20 M3 Bolts 2ea DIN934 M3 Nuts I used 5v fan and soldered the wires directly to the laser head power input which is 12v. 5v fan rotates faster and more efficient when supplied with 12v. 12v fan may be insufficient as an air assist. Simply glue the required parts together with a super glue.
