Must have upgrade
I purchased this item after having done some minimal hacking in the infamous "K40 - laser from China". For me, this was a drop in replacement that required no modification to the machine. I would suggest a better drawing showing where the lens goes as I had a little trial and error here. There was a spacer ring the I ended up removing because with it in place, only 1-2 threads engaged in the lens housing. Be gentle and only finger tighten the lens portion. I would also strongly suggest buying a mirror, lens and tubing at the same time. lens: LSR-LEN18ZN5I mirror: LSR-MIR20MSI tubing: LSR-WTUBE5X8 This works well paired with at least a 950gph (2cfm) air pump. A small aquarium pump does not have the flow rate.

Nice product
Well buit and executed device. Tried one that was 3d printed and it didn't work properly

Definite improvement over original
Used to upgrade my 40 watt laser. I tried two of the 3D printed options while waiting for this to arrive. Really, no comparison. This fit perfectly and is very tight. No adjustments needed and having the nozzle really reduces the smoke. We've used both an aquarium air pump and aquarium tubing with high volume and low pressure as well as a more expensive airbrush compressor with compression fittings with lower volume but higher delivered pressure. Both worked well. For our cutting application with thick wood and slow feed speeds the airbrush compressor works a bit better, but this is subjective.

You need a 12mm diameter lens
It says 'The laser head is capable of hosting a 18mm focus lens' I assumed this meant 18mm in diameter as a focal length of 18mm wouldn't reach past the air assist nozzle. I couldn't see how to get a 18mm lens to fit, no instructions to show how it might be possible. I bought a 12mm lens which fits. Product wasgreat once I got over the lens size issue.
