Laser Spindle Attachment.

Following on from my drag knife spindle attachement, I wanted a similar mechanism for attaching my laser (3.5W) to my spindle using a ring clamp. The spindle is an 80mm 2.2kW water cooled spindle and the ring attaches to the collar (narrower and black) at the bottom of the spindle.

I also needed a hood which serves two purposes. It helps direct the airflow from the cooling fan onto the cut/engrave point which helps clear any smoke and helps prevent burning along the edge of the cut. In truth it does not work nearly as good as a high power airjet right in at the cut but it's better than just the fan blowing over the cooling fins. The second purpose is to act as a shroud and helps stop laser light from bouncing all over the place. Let me be clear !!!THIS DOES NOT REMOVE THE NEED FOR THE CORRECT SAFETY GLASSES!!! when using lasers. The hood should just slide fit over the heatsink.

I also included some brackets to hold the driver board. Before printing you need to check your
