I dont have your light, but share your interest in small rings
I found some small keyrings at a locksmith, but sometimes they snag and stretch open between the winds a bit.
You may be able to see that in the pic, on the copper light. the titanium light also uses the same small keyring
note on the purple light I used a Jump Ring (that I took off part of the keychain the light came with)
Jump rings are a craft and jewelry store item, unless you take one off a spare keyring you may have
in jewelry work, jump rings are often silver, and get soldered shut, but the one pictured is stainless, and wont stretch open easily at all, unlike sterling..
because I prioritize tailstanding, I tolerate the angle of the dangle, even though I agree, its crooked!
I hope you post a pic of your solution
