The advantage of 3D printing is you can iterate as much as you want for a small cost.

Use good engineering judgment : make it 5mm thick, use 3 shells. For materials, use nylon or PETG. PLA melts too low, if the table heats a bit, you'd take risks. For a wide flat part like this ABS is not the best choice and might be tricky to successfully print.

If it doesn't work, try again ;-)
