I've been looking for one too. What size lens do you have? I have an 18mm, but the closest thing I could find is this assembly for a 20mm lens. Although the tube that is included might not match, I think the nozzle should be the right size threading if you have a 20mm lens.

Than is interesting Dustin- I am having a spacer machined for the Bodor that I wrestle with that will do the same thing as the spacer shown in your link. But... they seem in intimate that the spacer adjusts the focal length of the lens (I think it changes the nozzle position) and also that there are two places to mount the lens inside the main tube (which makes more sense to me). The second screen grab is for the 25mm tube which is very close to what my tube is on my 130w machine- and that shows two spacers which they claim adjusts the FL of the lens. I may order one just to see what is going on. My lens is 20mm BTW. Gene

but the question is if this set fits to KH-7050

Gene - yeah I didn't understand how they were trying to imply that focal length had anything to do with the length of the tube above the lens, but the spacers do seem interesting assuming you can put the lens in any of them.

Alexis - That seems like a lot of work to achieve swap-able nozzles!

Dustin- I am pretty sure they are just spacers to get the nozzle different distances from the lens- they seem to be saying that there are two positions in the tube that the lens can go- does not seem possible to me.

Alexis- the problem my be with the length of the cutting head if you do not have a lot of Z travel. Gene
