I created those two handles, so that they can easily be imported into Bambu Studio or any other slicer. In my case the original ones were not broken, but they look ugly in my opinion.
I created the STL for the rectangular lever from the 3mf file provided in the Support section at Bambu Lab: https://wiki.bambulab.com/en/x1/troubleshooting/front-panel-handle

The Lid and AMS is not provided here, so i created those.
In Case you want to add a logo or Text, you can do it in the slicer instead.
I added an example for the 3mf file.
Regarding the settings: Those are parts that don't need any support, infill was defaullt, but i wanted to add a hint for multicolorprinting: I used carbon enforced PLA and another noname white PLA, it was a great attempt to keep the tool and build plate temp at similar levels.
