Square academic cap / University / School Icon

## Icon Request

* Icon name: Square academic cap (According to Google, this is the actual name of those hats, however it wouldn't be too good for an Icon probably; Maybe something like `university`? I'm not too good at this, maybe someone else has a better idea?)
* Use case: This could be used in many contexts such as for online courses, for a knowledge base etc.
* Screenshots of similar icons:
(`school` Icon from mdi)
