Thanks RobA, nice finding!
I also found plexiglass balls, at more affordable price, but not larger than 60 cm:
But I can't understand if "QUASAR GRIGIO 600 MM" is spherical or not.... It's in the list, but not on the site?!?
It costs just 33 euros... Would be cool!
They don't sell cheap cardboard globes anymore? They're two high density paper product hemispheres held together,... I'm sure you could find something like that for sale somewhere, I remember having 14 inch one at one point, complete with textured surface. But I guess maybe such things have fallen out of production in favor for digital versions?
Sorry, you had said something about 40cm before, and that is closer to 14 inches than 20.
You could always do the math and cut out rings from cardboard, and stack them in a rough sphere, then put a few layers of paper over them. This would likely yield a ball stronger than a lot of options you could come up with.
That's the cheapest craft sphere over 20" I can find.

Yes, I also thought about this; it would be a VERY heavy ball!You could always do the math and cut out rings from cardboard, and stack them in a rough sphere, then put a few layers of paper over them. This would likely yield a ball stronger than a lot of options you could come up with.
Styrofoam would be better... if it wasn't that hard to cut it in circular shape!
The problem with those is that shipping is going to be hellish at best.
If you have a good steady hand, and a large table you can use for a work space, then making a stacked cardboard globe is likely going to be your cheapest way of getting a good, strong globe. Get some corrugated cardboard, do the math for the size you want and start cutting out large circles that you can stack together. Save weight and material by then cutting smaller circles out of the middle of your larger ones, but leave a solid sheet every now and then. (Space them 4-5 inches should be fine) Make each circle say, and inch and a half, two inches wide. How many layers you use, and how much difference in diameter there is between each one depends on the thickness of your cardboard.
Save time and cut two layers at once, one for either hemisphere.
Good luck with your project, I'm thinking I might have to do this myself to get a better idea of my novel world. It would be easier than working on 3D models for it.
They don't send to italy... becuse they say the big ball is too fragile and it will break apart.Originally Posted by jumpjack
...so I told them I don't care if it breaks, I'll just... build the puzzle , as styrofoam pieces can be easily stitched together, without leaving any junction visible.
And even if they are visible, I'm going to cover the ball with paper, so who cares?
The replied they'll think about it...
