Question: I would like to show 'Low Stock Notification' on my website.
I have set 'Only X left Threshold' globally.
Is there any possibility to set this for each product individually?

Answer: 
Although Khoa TruongDinh's answer was really helpful, there are some details missing so here is a full example:

Working minicart example, copy the html template to:

```
[theme_path]/Magento_Theme/web/template/minicart/content.html

```

and in themes requirejs-config.js =>

```
var config = {
    "map": {
        "*": {
            'Magento_Checkout/template/minicart/content.html': 'Magento_Theme/template/minicart/content.html'
        }
    }
};

```

Open file for modifying minicart contents: 

```
/app/design/frontend/your_theme/Theme/Magento_Checkout/web/template/minicart/content.html

```

Open file for modifying minicart product contents :

```
/app/design/frontend/Eglo/Theme/Magento_Checkout/web/template/minicart/item/default.html

```

After modification, You have to deploy the theme using `bin/magento setup:static-content:deploy`then it will show.

If modification is not populated then modify tempaltes in below directory for showing runtime changes:

```
/pub/static/frontend/Your_theme/Theme/en_US/Magento_Checkout/template/minicart

```
