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 ;-)

I forgot to mention something really important. I don't have a 3-D printer. I was going to use a 3-D printing service since I don't have many projects planned for the future. So I need to have a better idea of whether this will work without being able to make and learn from mistakes.


So what are the vantages and disadvantages of nylon and petg, and which would be better for this project in terms of weight and strength? What is the problem with ABS?


Lastly, what do you mean by three shells? I'm not familiar with that term in this context.
