K40 Laser Cutter New Lens mount

This was designed to replace the lens mount on the K40 "Cheap Chinese 40W CO2 laser engraver/cutter." With this, you can either install the original lens or swap in a diode laser mounted in the popular aluminum diode heatsink like the one in the photo from Victoryrush on ebay (where I purchased mine from.) The heatsink should be suitable for 1W or less diodes.

Will work with either. The K40 lens tube is 15mm at the point it mounts in the holder. Between the fins of the aluminum diode heatsink
