When I printed the yellow one, I noticed a crack between layers about 28mm from the tip. This is caused from the warping that occurs (from temperature change) while printing ABS. I threw it and one drop cracked the top. I figured I could glue it together, but then decided it would be more interesting with the tip on the top "crownless". I was amazed it actually worked well, and I think I liked it better. This was a great discovery for me and opened a new door for top shapes. I am currently printing a green PETG version that is based on this shape. While the yellow one is just taped together with electrical tape, it is a fantastic top.
The green top in the video is a similar shape to what the yellow top was supposed to be, just a bit lighter and different weight distribution. I like the green one a lot as well. It is basically the red top I made lengthened by about 12mm.
The red top is great but had a vibration that was intensified when I made heavier versions. This made me question the design and what variables I could use to accurately predict if a shape will be stable or not. I am going to find the center of gravity for a few of the tops I have made to see if this is a predictor for stability. I figure I will take a few of the good players and compare them with some of the versions with vibration.
I am sure some of the people turning wooden tops have gone over this. I would love to hear some advice on design.
I would be open to a collaboration if people have ideas on shapes I am not thinking of.
