Hexagonal prism

I’m hoping to create a hexagonal prism using pixel art, but I’m a bit stuck.
I’m bothered by the straight lines being so hard in contrast to the diagonal lines.
How can I balance this out? Any tips on drawing this?
I’m still quite inexperienced with pixel art, still on the first course.

The difference in contrast is really an optical illusion if you’re using the same colour for all of the lines.

But if you could try increasing the thickness of our lines.
