#12 Ball 4 by PETER LAKATOS
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

Could we have some ratings please ?

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

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.

Design a Dynamic Mini Golf Set!
Hi Cad Crowders I would like to have one of my ideas designed. It is a physical mini golf (putt putt) game that is made up of several pieces that can be assembled together in different combinations to create different playing surfaces. The mini golf game would be suitable for use for fun at in places such as homes, offices, garages and schools for fun and putting practice. - There should be around 12 - 15 sections/pieces in multiple shapes. - Mostly square shaped pieces, approximately 700x700mm - Some other shapes including triangles, semi-circles and miscellaneous which can be attached and used for changing direction. - Some pieces should have vertical rises and falls for added challenge in play - Some obstacles (basic cube or triangular prisms) for added challenge - Pieces could be connected by magnets - The course should be green coloured (like a putting green) - Design one of each of the following pieces: square, equilateral triangle, semicircle and a couple of miscellaneous shapes. - Each piece should be capable of joining to any other piece (i.e. the sides should be the same size) - The idea is that all sections can be attached to each other in many different ways so that there is a large number of possible arrangements for playing. The final piece should have a hole for the ball to enter as well as a small flag. The attached drawing is a VERY basic concept. The shapes are a top-view of some various shaped pieces and how they could possibly fit together to create a certain configuration for play. This is only one possible combination - the idea is that the pieces can be arranged in MANY different ways to make different games of varying difficulty. All the best! Thank you
