This version has the core in a cilindrical shape.
I can update any design, perhaps use the outer texture of the first ball on the others. I welcome any suggestions or feedback you may have.

Peter, you referenced "ratings". I don't know what that means, this is my first time on the site.

Jnatzic, yes the outside should be solid.

And for all of you....can this be made with material that is similar to a stress ball?

Thank you all. Your ideas are great. I will decide soon on wobbly ball, and I will need some additional work to design in the near future.

Do you have a preference whether the outside of the ball has openings in it or is solid? Thanks

The ball should be made out of a plastic material, in between soft and hard.

CROISSANTERIA DO BAIRRO
Need a Bakery Kiosk (4x4m^2) design/futuristic/minimalist look, with shape of croissant on the ground. Maybe cork material. Please keep this simple, to have costs and time to make it faster. The kiosk itself is limited to 4x4, the floor can be bigger. It is for a shopping mall. It is a French Chef Bakery/Coffee Shop that serves croissants, chocolate and coffee. Attached are some pictures of the feel we look for. We need the implementation in 3D and 2D measurements to send to the Shopping mall Administration for Approval. THIS PROJECT CAN'T TAKE MORE THAN ONE DAY. IT IS OF EXTREME URGENCY! NO BS.
Shoe design
I am looking to explore the idea of "reinventing" shoes. I'm looking to create a shoe that turns from a heel to a flat. In order to do so i need a mechanism for the heel to flip out and lock into place from a groove on the sole of the shoe. The heel itself would be based on a lever where you can push the heel into a groove of the bottom of the shoe to make the shoe a flat. Then click it out using a very simple unlocking system on the sides of the shoe ( a bit like when you unclick the lid of a calpol bottle pressing on both sides) to make it into a heel.

Mechanical jewellery
I have two 3d ring designs with a moving part. I would like the rings to be printed in steel and assembled after printing manually such that the moving part is inserted easily in the ring. Manual assembly can involve a lock, a latch, or screw mechanism that snaps the ring together never to come apart. The rings will be printed on shapeways.com.
