Hollow Sphere Design for 3D Printing

grabcad

Greetings! I require a hollow sphere blueprint featuring detachable upper and lower sections. The sphere will be constructed from plastic and filled with sand (refer to specifications), so the connection must be strong and unbreakable once assembled. Aesthetically, I seek an attractive design for the sphere itself, particularly focusing on cutout patterns (as depicted in my hand-drawn sketches). Kindly use Autodesk Inventor Professional 2018 for this task.
