An isometric grid pattern.
Useful for planning objects in 3D, as a guide for technical drawings, or just nice to look at.

Example of use for planning a space. (The 3D figure is not included in the pattern.)
This pattern is not pixel-perfect, but it's close. All the lines are even, with no stretched or squeezed sections. You can rotate the pattern and it won't suddenly look strange.
I hope this pattern is helpful!
