>>10217702I like to fiddle with my twisty puzzle collection throughout the work day since I work from home. Usually helps me to feel better when things get complicated.
Main brand Rubik's cubes suck horribly though but the Chinese ones are really good like my pricey 3x3 GAN cubes. There are some good budget 3x3s out there too though that also feel good.
I also enjoy my YJ MGC 2x2, 4x4, and 5x5 cubes which tend to be cheaper but are considered some of the best non 3x3 cubes.
There's an ass ton of twisty puzzles to check out that can be used as fidget toys and feel pretty rewarding to learn to solve when you're not fidgeting with them. If you're in the US, speedcubeshop and cubicle are both good online retailers for them.
