I know AixiZ are always going to have loose lenses because they aren't premium quality, but does anybody know if there's a way to maybe make the lenses fit a little tighter?
A turn of PTFE tape will do it, the sort plumbers use.
I bought some glass lenses, they are in a brass housing and are a much better fit.

There should be a spring in there to maintain lens to housing tension. The teflon tape works good for me. Just be sure there are no shards of tape in front of the LD.
I wouldn't have thought that white teflon would burn, but sure enough I guess I got some small shreds in front of the LD once, because the next time I opened it up, I ended up having to pick little black threads of stuff out of my open-can. Very delicate procedure that. The surprising thing was I hadn't seen any decrease in output.
After that I took to just messing the plastic threads up a bit with a soldering iron to make it a little harder to turn freely.
I always wondered about having that spring in there - if that would absorb any of the output. But I guess any it would have absorbed would have been off-axis anyway. Now that I've got a meter I guess I can measure to see if there's a difference with the spring.
Is the spring still in it? I had one like that to, and here is a barbaric mod that actually fixed it, but be careful when doing it. Down the threads of the actual lens parts, take a knife and smash down the threads a little bit in a line. Don't over do it, just do a little bit at a time until you find a "setting" that best fits for you. Look at my attached paint masterpiece.
