INITIAL RELEASE (5/21/2023):

Not sure how many people will need this, but it seems to be a common problem with the Mamaroo rockers. Anyhow, I printed this out and super glued it to the top of the socket where the mobile is attached, and it props it up just enough to keep it out of baby's face by replacing the face that fails. The level of failure may vary depending on how long the wear has taken place, so you may need to use the cut feature in your slicer or tinkercad to make it thinner. Printed with 100% infill.
