JLC3DP Broken Surfaces

[JamesN58]

I'm trying to get a mx case printed by JLC3DP, but it keeps getting sent back with errors. Specifically the left tray. I don't know how to adjust it or even what the problem is. Any help would be appreciated.

Iirc this is because some of the walls are a bit too thin for JLC. I believe others have pushed them to print it as-is and it turned out fine, but it likely depends on the specific method you are trying to get it 3d printed with. I believe for FDM JLC's spec is not that great, and you may wish to use a private more local service who can tune it better and actually use the recommended nozzle size and layer width. JLC is only recommended in the docs for case printing because it's already used for the PCB, and because someone tested SLA for me - my cases I printed FDM at home.
