Attention: This modification is not by me but by my friend Jerry, aka Yezi as Chinese name. He don't have a TP account & don't know much English at all. So he ask me to make a post & translate for him. For the original post on mf8 forum you may take a look at here.

Here is my translation:

Talk about Impossiball with friends, suddenly I din't know where my impossiball is & while I found it out, some inner pieces, including the core has been broken......What so fortunate is that those pieces can be glued but I don't think it is strong enough to turn many times. So I decided to use this ball as a material to do some mod. The idea is to stick each piece with a Triangle, thus make it into a Isocahedron.

My friend DDR recommend the name "Golden Isocahedron" after I show him some pics. I think the name is good to describe it as well~

Here are some pics:

Firstly, I sand the original corner pieces of the ball to make it more round. I do this because I'm afraid the broken core is too weak to afford "break-in turning".....I don't know how to describe this turning but if you tried impossiball before, you'll know what I'm saying. Rounding those corner pieces will decrease resistance while turning, I think.

Secondly, cutting & sanding pvc sheets. Of course I have to test & compare each of them at the same time.

Very nice looking, and surprisingly simple!

I have to say I'm not too much of a fan of the stickers though.

This looks like engraveable plastic, much like what we use in our shop. I think laser engraving the plastic would look much nicer than the stickers.

Yes, here we called pvc color plate thickness is 1.2mm, There are many color choices, gold and red, laser cutting will be more suitable, thank you for your reply. :D

Jerry:
Be careful! You should not laser PVC plastic. PVC = Poly Vinyl Chloride. Anything with Chlorine in it will release Chlorine gas when lasered which will not just scar your lungs, but also etch the lens of the laser which makes subsequent cuts unfocused and weak.
Acrylic is a safe plastic material to cut.
