I'm up for recommendations on fidget-style trinkets that are actually good. Like, machinist level good if they're mechanical, or with brand name parts if they have clicky switches and levers.
I love to toy with stuff in my hands but I have stupidly unreasonable standards unfortunately.

@nadia I'm gonna be honest, the best fidgety thing I've ever had on my desk was a mouse ball. Like... A 90s computer mouse ball. I have a little coaster that sits on my desk and it has a lip around it and I can roll it around on it, but I also pick it up and toss it around between my fingers and stuff. They're very heavy for their size because they're basically an iron or steel ball coated in rubber for grip on thr mouse pad, so I can also weigh down a key on my keyboard with one if needed

Edit: they're also extremely high quality due to the requirements of being a mouse ball (must be very spherical and very smooth but also grippy) and have no moving parts to gum up or be loud or get damaged.
