You have created a family of curtain-ring tops!
Besides the commercially available "exclamation mark top"and the PERIOD top (curtain rin top nr. 1) this "colon top" is the third punctuation top I know of, can you think of any other ones?
I cannot find the post, but we once discussed this top offered on the Shapeway marketplace, the
Less is More spinning top:
I like its looks, but the dynamic balance cannot be perfect along the axis. It still manages over one minute and a half with less than 2 grams of weight.
They also have a medium size and an
extra large version.
When we originally discussed it, I tried to order one but the order was later canceled because they could not make it in the material I had chosen
I don't recall the material I selected but it definitely was not solid gold
Edit: I checked my Shapeways history and the material was polished bronze steel. It seems that the problem was the "polished" part, so the creator removed that option. I ordered again but it will take a month to deliver.
