This replaces the brittle and often broken black plastic piece on the inside of the CD book browsing pages assembly on a Rowe/AMI Laserstar Eagle CD100 Jukebox. It may work on other models, but none that I know of.

The old parts break when the page turn mechanism is tightened down into the plastic. These new parts are stronger and more flexible and you can reliably tighten it down, although they will still break if you overdo it.

Print with 100% infill. I used PLA and it worked fine, but ABS would probably also work.

You can see a video about this part here:
