Tell us about yourself!
I did it!! Thank you for the tutorial! I have the Nikon AF-S Nikkor 18-105mm 1:3.5-5.6G ED lens, and bought a plastic replacement ring of eBay or something for €2,- or so. Half way the repair the lens came apart further than I indented, but fortunately that was fixed by unplugging the ribbon cable from the Auto/Manual focus switch and unscrewing it, fitting the plastic ring again, and plugging/screwing the button back. In short some freighting moments, but I got it in the end :D. A tip for people who are going to attempt this: keep the lensparts (zoom ring, focus ring, etc) tightly together, don't pull any up.
