Sometimes I find people looking for such a brush. It’s a little bit tricky to make it and hard to explain, so I just share it here.

That is very cool. I’ve seen numerous people looking for a brush like this. Thank you for sharing it.
(I moved it into the brushes section of the resources category.)

Thank you for sharing your work.
But you should really think about changing the nature of the link, because currently users have to provide their email address to download your brush, and that’s something many would understandably never do.

does making a brush like this include coding?
Why should that be? As you can see, all settings of this brush are solely based on its settings.

It uses a Masked Brush with the Brush Tip set to Subtract blending mode.
That’s a neat trick and you can do cool fun stuff with it:

ahh ok that makes sense
Well, the real tricky part is that my brush keeps the width of edge constant when the size increases(I mean increase size by pressure while drawing, the edge gets wider if you press “]”). If you just put a smaller tip on the top with subtract blending mode and same pressure line, it would look like the upper line in the picture below.
The trick is to shift the pressure curve right a little bit, make sure it’s parallel to the curve of the base tip:
I just noticed that the bush preset I uploaded doesn’t strictly follow the rule, and the edge width just looks approximately constant. I made it a long time ago, maybe I have changed something and forgot about it. But now you get the point and can modify it by yourself.

Thank you sooooooo much! I was looking for this for a long time! I loved it! 
OHHHHHHH thank you!
Is there a way to make it filled?
Hello @OrganicTrash and welcome to the forum 
What would you want it filled with?
Any color, like how shape tools can be filled in
For more complex situations like that, I suggest to use a desired brush (usually hard-edge round brush), and use Layer Styles with Stroke. The only downside is that you can’t overlap strokes, they would merge into the same shape and the lines would disappear. However, you can duplicate the layer, clear it, and continue there.
Thanks for the workaround!
