K40 upgrade
Unavailable in the UK but amazed how quick order arrived. Many UK suppliers are much slower. Excellent value even allowing for UK postage. Recommended retailer

Perfect upgrade
Before I purchased the K40 I saw this air assist head and decided I would try to make my own first. I thought it worked well until I got this head. The lightobject air assist is amazing! I bought it and the Improved 18mm ZnSe Focus lens (F50.8mm). The laser performance increased dramatically. I am able to cut at a third less mA with zero build up on my lens. I waited longer than I should have to buy this. If you're getting a K40 laser I suggest you set aside the money to order this head and a new lens at the same time.

Streets ahead
There is no comparison with the original k-40 head. The machining on the original was abysmal with the mirror recess 1mm deeper on one side than the other and the nozzle outlet drilled offcentre. Excellent replacement.

Great value
Nice construction. The lens cap was screwed on too tight and it was a bit of a job to get it off without damaging the threads on the housing mount but with some care, it was possible. You may need the lens adapter for the 12mm K40 lens. You can get an STL from Thingiverse.
