Accessing Ember-Data Model Blueprint in cutom Blueprint

Ember CLI
1

Hi there, i try to generate an EmberData Model from inside my own Blueprint. The examples i found so far seem outdated, since Blueprints moved out of ember-cli into corresponding Addons.

What i tried:

// Blueprint index.js

const Blueprints = require('ember-cli/lib/models/blueprint');

...

let modelBlueprint = Blueprints.lookup('model'); // unknown blueprint
let modelBlueprint = Blueprints.lookup('model', {paths:'ember-data/blueprints/model'});  // unknown blueprint

Ember Version 3.28

How can i access Blueprints outside the scope of ember-cli?
