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: 
You can override this by adding this folder to your theme:

```
Magento_Checkout/web/template/minicart

```

In this folder you can create the content.html file. After a change made in this file make sure you flush your browser cache to see the changes.
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

```
