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.

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.

The job is to convert the DWG-Files into an Allplan-Nemetschek file ( software from 2015 or older ). That means it have to be a working 3d model. There is no need for an outdoor area, material surfaces or rendering settings. Just the building have to be in nemetschek so we can import it. Thanks for your attention and kind regards.
