Mount to use the Cloudray K-series laser head on my k40 laser cutting machine.

Sorry, I didn't set the units correctly. You will need to reduce the stl file needs to 10% when slicing. I sldo included the Fusion360 partfile for remixing.

This laser head is $25 from cloudray or $15 from aliexpress.

I recommend the version with a 12mm diameter lens. This version has an adjustable depth allowing you to set focal distance to your workpiece without adjusting the bed up/down. The 18mm diameter lens version does not have adjustable depth.
