When printer Pauses, be sure to double check that keyring is not poking above print surface, keyring does not have to freely rotate as a second ring will loop on this one.

My example has been on my every day use keyring for well over a year.(or two)

The embedded keyring provides a much stronger connection to the 3d print.

the pause must happen RIGHT BEFORE the channel for the ring is printed over.

--The keyrings I used are("CleverDelights 1 3/16" Key Rings - 100 Pack - 30mm Strong Key Chain Ring Connector") (can be found on amazon)
