Heroku, django-storages, and s3: Collectstatic works locally but not on Heroku

Question

I followed the top answers here and here and everything works as expected when I collectstatic locally but not when I collectstatic from my heroku instance.

My settings.py and s3utils.py files both live in the myproject folder which is adjacent to the main manage.py.

s3utils.py:

from storages.backends.s3boto import S3BotoStorage

MediaRootS3BotoStorage  = lambda: S3BotoStorage(location='media')
StaticRootS3BotoStorage = lambda: S3BotoStorage(location='static')

settings.py

DEFAULT_FILE_STORAGE = 'myproject.s3utils.MediaRootS3BotoStorage'
STATICFILES_STORAGE = 'myproject.s3utils.StaticRootS3BotoStorage'
AWS_ACCESS_KEY_ID = 'XXXXXXXXXXXXXXXXXXXXX'
AWS_SECRET_ACCESS_KEY = 'XXXXXXXXXXXXXXXXXXXXXXXX'
AWS_STORAGE_BUCKET_NAME = 'myproject'
AWS_PRELOAD_METADATA = True # necessary to fix manage.py collectstatic command to only upload changed files instead of all files

STATIC_URL = 'https://s3.amazonaws.com/myproject/static/'
ADMIN_MEDIA_PREFIX = 'https://s3.amazonaws.com/myproject/static/admin/'
MEDIA_URL = 'https://s3.amazonaws.com/myproject/media/'

When I run collectstatic locally it successfully copies all my files to s3. Here it is again and you can see it worked:

(venv)robbie@ubuntu:~/git/myproject$ ./manage.py collectstatic --noinput

0 static files copied, 5357 unmodified.

However whenever I deploy and visit my site or try to run collectstatic through heroku I get the following:

(venv)robbie@ubuntu:~/git/myproject$ heroku run ./manage.py collectstatic --noinput
Running `./manage.py collectstatic --noinput` attached to terminal... up, run.5714

    raise ImproperlyConfigured('Error importing storage module %s: "%s"' % (module, e))
django.core.exceptions.ImproperlyConfigured: Error importing storage module myproject.s3utils: "No module named s3utils"

Any help would be greatly appreciated.

Nevermind, it was a stupid mistake but I'll leave it here in case anyone else stumbles across this, ready...?

Be sure to add myproject/s3utils.py to your git repository after you create it!

I am not a smart man..
