K40 china laser air assist with fan

myminifactory

This is a dedicated air assist for the China-made laser known as K40. It's specifically designed to work with direct-mounted fans that can be connected directly to the 5V output of its power supply. It comes equipped with integrated brim and doesn't require any support material to print, making it ideal for use with well-known radial cooling fans used in many 3D printers. To mount the fan or nozzle to the laser head, you'll need to use M3 screws. One potential drawback is that the air assist system can actually suck in ambient air instead of fresh air from outside, which might be a concern in certain environments.
