Finding a Custom Object Id (01I…) to get the Setup page URL

I’m trying to find a way to get the “Id” for a custom object’s setup page. So I’m NOT trying get a record Id. I’m working on a custom visualforce page and I’m setting up a link so that when the user clicks it, it’ll direct them to the object’s setup page. I’ve included a picture below to show what I’m am trying to get.
