Hi, about this A4000 keyboard case design, After buying the files from you, and submitting them to JLCPCB for printing, they have come back to me warning of a very high probability of warping due to the design. Can you confirm you or anyone else has had this printed successfully? This is what they have said:

Hello customer,
We hope this email finds you well.

Sorry to bother you, but there are some details that we need to confirm with you about your 3D printing order before proceeding.
As shown below,
the parts has high risks of deformation and warping because of the geometry, will this risk be acceptable for you? Shall we proceed as per your files?
Usually, for flat parts, frame parts, enclosures with no strong ribs inside, and large unoccupied areas parts, and the models could be shrinking to the center and warping to the diagonal lines and edges. Kindly recommended that it is better to increase the thin wall thickness at least 3.5mm ,and add strong ribs to strengthen the structure of the parts.
