Very nice. Purple Rain has a nice shape.
I went back to the shape used for the smaller top. It is very stable and fun.

Wow! That is a big top! It must have taken quite a long time to print.
The shape reminds me a Chinese tuoluo.
Impressive!

Fantastic work, both in the shop and on the string.

Have you considered a larger hole in the crown to lower center of gravity and also increase accessibility?

Cecil,
I did make the string and here she is in action.
Threw this together this morning.

spiffy to the max  8)

Here are pictures of Rev2.
5.2" diameter / 5.4" tall (without tip) / 229gm
.2mm layer thickness with 60% fill.
2mm wall thickness with 5mm at the shoulder for better stability.
I had to make a bit of a thicker string for her but she is worth it. More stable than Gladis. This one shall be named Purple Rain.
I have Rev3 all cadded up. Hope to get it printed soon. It will be a different shape than the first two.
I tried to take pictures of the process bellow.

lincolnrick- Thanks

ta0- The tops shape does have that Chinese look. It's supper stable and a great top. It took 18 hours to print so it is time consuming.

Neff- Thanks. I scraped Rev3 and went right to Rev4 with your recommendation added. I made the crown larger. It's printing as I write this. I am excited about this one.

Jack- How did you know I am a Star Trek fan :)

Well I have the blues.  :(
~140 gm and 4.5" wide. As you can see a larger crown hole, which is cool.
The only thing is she is a bit unstable but still playable. It reminds me of how the short circuit acts when you put in the aluminum tip.
I have made a few mods and am already printing another.

Big blue!  8)

If I am not mistaken, the tip is fixed in place with a washer and a hex screw. Get a longer screw and place a couple of nuts to make the tip heavier. If the problem is that axial and transverse moments of inertia are the same (what we suspect happens with the short circuit), this could fix it (or make it worse  ::) ).

This top looks very straight-sided again, like the orange one you made earlier.  I thought you got better performance out of the more curved profile, like you used on the white one and the purple one....

ta0- In my next rev I made the top 10mm longer and added more material around the shoulder. This seems to have solved the instability so I claim success on this shape. When I can get more tips I can see about trying to fix Big Blue. I am considering just going to emachineshop.com and ordering tips.

Jack- When your right your right, I get obsessed. I make the string the old fashioned way with a 2x4 , hooks, drill and a lot of room. I get good results although I am limited to about 8' strings.

mailman- I have gotten really nice results with the round shape for the smaller tops and decided to try it for a large top. The large top plays great although I wanted something more maneuverable for certain tricks. The material that bulges out around seems to make certain moves more challenging. I think this latest version I made is great but I will have to play with it a bit more before I decide if there will be more revs. I am currently working on a smaller version of this top, (think jumbo short circuit). I think this could be a fun shape.

Sabaspin - Thanks!


Well this is the latest Rev. 165gm, 4.5" in diameter and 4.75" tall (without tip).
Stormy might me a good name :) Time to go test her out more.

One top is 8.0 inches the other is 10. 1/2 inches. I really missed the shape on both these tops. The clear one has to much of an angle, and I don't like the crown on the big one. Not enough radius. That's why I allways need to make another top. I think you know what I mean.

I just don't like the look of the straight angle.

Stormy weather never looked so good!

Big mouth tops are very convenient. When traveling you can stack several or put smaller tops inside. And if you are stuck in a raft in the middle of the ocean you can use them to catch rainwater in stormy weather. >:D
