Since textures.com hasn’t given me any free credits despite my account having been made for multiple days now I decided to try something new, downloaded GIMP, and followed a tutorial to create a texture of my own.
In use I still wanted the metal bars (there is a way to make them in GIMP, and I did try, but ultimately decided against the additional time on it for now) so instead I added two additional loop cuts (after the beveled two for the shape) and set them to a different material slot and added a metallic material to it instead.
I included my attempt at a texture in case anyone else would like to use it.
