Product Description
Aesthetically, the HV2 from Designs by Dalton is about as unconventional a spinner as you could find—but the design isn't just for looks, it's also the secret to this air-assisted top that spins faster if you blow air through it (see video below). Crafted from 3D-printed steel with a burnished finish, the spinner is a matrix of metal that’s as appealing as it is eccentric Read More

Whats the best bearing to get and does it really matter? Would be grateful for any input from those who obviously have more knowledge than me on this topic.

Do people really carry around spinning tops with them? Why? Seems stupid to me.

This isn't a new arrival. This pile has been around since the fidget spinner obsession.

The video is misleading. After it's twirled, it appears to speed up, but that's a stroboscopic effect of the video frame rate. It's the same effect that makes wagon wheels appear as if they are rotating backwards in movies and videos.
This perforated structure is somewhat of a two-edged sword. The perforations allow it to respond to blowing, but they also have more aero drag than a solid top, and thus a shorter spin time.

Alan24This is a little off topic, but here’s an explanation of what’s going on with that “Wagon Wheel“ effect.
The illusion of slow, slowing, stopped, or reverse spinning due to coinciding frequency rates between the rotating spokes and the frame capture rate of a camera, or the strobe rate of a light, are well understood.
More interesting is when you see this in real life, where there is no frame capture rate or flickering or strobing light.
You can often, for example, see this effect in real life on car wheels when driving down the freeway. That’s in plain, continuous sunlight.
An explanation is provided here:

Very cool top, by the way.

Very cool! This thing looks like it came from another planet. I would get it if for not for these rubber gaskets on the stem , it ruins the overall design concept for me. I understand the reason they were put there, but I much prefer the stem with some simple grooves instead.

BlueCrownedOf course I can, but then it would be just a naked short stem without any grip to hold on. This perfectly round stem does not belong to alien-like design, IMO.
3D printed steel? how does that work?

CalaverasgrandePretty cool stuff. I've printed a few SS items on my mk3. The filament is wicked expensive though. Here's a good link for an explanation: https://all3dp.com/1/3d-metal-3d-printer-metal-3d-printing/

Dug up faucet handle out in the yard. Now I know where they got their design from .

It's very cool but o-rings? Really? Was grip an afterthought? Would printing some knurling on the stem be too hard?
KnutThe o-rings are optional, but I personally enjoyed the look of them. They provide extra grip but are not necessary. Black is my personal choice, but I think you should be able to find plenty of colors to customize it with if you didn't like the standard black. Lobster is right about some knurling being hard to print, but I have had successful attempts like The Zephyr. Good to know that some people would rather see a knurl than have optional things!
