Hi all,
For one of my projects I needed a Lego ball. But not a massive one, it should be light weight. Searching the internet, I found a Pinterest site containing all sort of Lego spheres: https://www.pinterest.com/pin/530369293592753126/.
Based on the black and red rhombic triacontahedron (don't worry if you don't know that this is the official name of the sphere ;-), I made a green version. I included the 1x6 bow elements (41762) which makes the sphere almost perfectly round, making the ball roll easily on a floor.
A photo of the real one:
I created the ball also in LDD and had it rendered by the application that just had been released Stud.io (you can read more about this at Bricklink: https://www.bricklink.com/v2/article_view.page?id=1009). The result is really nice (if I hadn't made this picture myself, I would have thought that it was a real photo):
I made a small Youtube movie so you can see that the ball rolls really good:
Enjoy,
Hans
