Fusion360 Triangle pattern

Hello!I'm trying my hand at making my own GPU cover. I would print it on the 3D printer at the university.https://a360.co/3TCDfo9You can take a look at the part there. I now have a question. I would like to install a triangular pattern in the 2 large, open areas to match the PC housing.The triangles are relatively small, 6 of them are arranged in a hexagon with some space in between.What is the best way to get such a pattern in there?And when I have finished, is it enough to press 3D Print in Fusion? Will I get a printable file?Many thanks in advance!

You will need to export the file from Fusion 360 in a format that can be read by slicer software, then slice the file to generate g-code, then put that file in the printer.
