A fusion360 file is available but only for my changes since it is based of the stl of the base model. It can be useful for further remixes however.

Printing Information:

• Use regular supports to properly support the petals

Note that the step file is quite heavy and might have difficulties to load, if it's the case try the stl which will be far quicker.

As I only really flattened the flower base, all credits go to the original author.
