I did not create these. These models were provided by Bambu Lab after it was discovered that the early versions of the AMS had a weakness in the roller supports and they had a propensity to crack and break. This is merely a mirror for the models and instructions provided on their wiki here: https://wiki.bambulab.com/en/x1/troubleshooting/reinforcing-roller-support
Please read the PDF snapshot of the wiki instructions thoroughly. This is kind of a janky fix. Don't blame me if you break your AMS.
