WTF I literally wanted to post the one you posted. What kind of witchcraft is this?!

I even love that it's quiet myself.

I call it chained keyrings, but flippy chain is more fun to say, thank!

Unfortunately mine is cigarettes

That’s no a joke I bet a lot of undiagnosed people smoke just because they have adhd.

I rarely end up using actual fidgets because I always forget them… so I usually just fidget whatever object is within reach at a given time.

Just one of those stick toggle switches.

I have a metal mini slinky that I love to fiddle with, it's definitely the best fidget toy I have

I am not sure I could pick a favorite but here is my desk’s current fidget toy box hah! If I had to it’s probably the fidget cube or whatever is in my pocket. Also, I’m going to need to know more about this floppy chain most importantly where do I get one 😄

I recently got a hard plastic smush toy i really enjoy

I also really enjoy the classic 3 lobed spinner fidgets. My longest enjoyed fidget is a bit smaller than a switch joycon and has a bunch of buttons and switches on it. I often have it in my pocket at work as i can easily fiddle with it quietly with 1 hand while speaking with someone

i've tried finding one i like for a while now, ever since i got a 3d-printer... i feel like i need something with more heft to it. weirdly the thing that has worked best so far was a cylindrical pill box which opens with a spiral motion. flicking the top makes it spin all the way open and it's smooth enough to close on its own.

Honestly nothing beats tapping drum beats with my fingers to my favourite songs all day. Also made my typing insanly fast and (mostly) accurate at work lol

My beard.

Without thinking, I pick at the skin around my fingernails. Sigh. But when I do reach for a fidget, I have a spinner and one of those Needoh gumdrops that is satisfyingly squishy.

Infinity cube. I've got loads of them. It really helps me listen when people are talking to me.

I have a small, pocket-sized fountain pen. In meetings I can take “notes” (draw), then spin the cap on and off. Some of the other people below mentioned smoking and it’s good for that too. I just say “sorry, I need a smoke” as I put the pen in my mouth. Nobody bothers me and nobody asks for a light. Worked a lot better before vaping was a thing though.

I like wearable fidget toys. I have an enamel pin of centrifuge tubes, which actually spins^[1]

I also have a couple of cool interactive pins from AtelierEumori (currently on break). I have this social battery pin and this TTRPG dice pin

There's a couple of rings that I have long been coveting, such as this one, this one, or this one^[2]. I don't own any of these, because they're super expensive, but they've inspired me to learn how to make stuff like this — I've been learning how to use a jeweller's lathe.

I like wearable stuff because otherwise I will forget them or lose then. I do have some begleri, which are as much as a skill toy as a fidget toy. This aspect of skill is why I like them — I like the feeling of practicing stuff. For this reason, a standard deck of cards is also something I like to fiddle with. Unfortunately, I tend to forget to take them with me, so I'm not actually very good at this stuff.

A dog clicker they gave me at my dogs training course a few years ago. It's louder than any clicky pen. So satisfying!

Rubik's cube was my favourite for a few years when I was commuting by train. I had a 40-60 minute trip each way for work and it was an amazing way of killing time without going mad.

Then podcasts and audio books came in and honestly, I can manage sitting still with audio playing. I need it to be stimulating enough, but running everything at 2x speed is fantastic and really makes a huge difference.

That said, I also have a notepad and pen so I can write things down while sitting, so I plan projects and write questions to be answered later. That helps a lot. I also have my phone which is great for passing time, Offline Games is a fantastic set of games that dont require purchases or ads. I also have my first aid kit on my belt and I regularly go through it and make sure all is well, along with my tech pouch. Organising those and cleaning them out works well.

I want to say clicky pen, not just for the clicking and spinning but also dis- and re-assembling them.

But the real answer by time spent is probably cocktail tray.

I have those too! They're fantastic!

I really like using a Rubik's cube.

Guitar

My cell phone.

I'm a drummer, so mine is usually just finger-drumming to whatever is stuck in my head at the moment. But when I do use an object, spinning a pencil/pen or bic lighter around the thumb will keep me busy for hours

The zit on my neck that won't heal because I keep picking at it.
