Yes.
Weighted blanket - I went to Ikea to try out the weights and then bought a cheap one from amazon. And blankets in general for when I get cold.
Headphones which I use like ear defenders. DH is a gamer so we always have an old pair lying around.
Deep breathing, not a kit obviously.
Piece of material with the right kind of edge that I like to rub between my fingers. I have always loved doing this but didn't realise it was a stim or was a self-regulation thing until I got more into the ND world. My mum reckons I did exactly the same finger-rubbing ritual on the edge of her shirt when I was breastfeeding - and it is always cotton shirts with a crisp fold, or pillowcases (the fold has to be crisp enough or the edge "sharp"). I was only breastfed up to 6 months old so have no memory of this of course, but I love the idea that it might link back to that, how safe must I have felt when I was that small?
Music that I like.
Spinny desk chair with high sides (Ikea Skruvsta) - DS likes to be spun in this too.
I always keep chewing gum in my coat and packs of suckable sweets everywhere. Stops me from chewing pen lids, my nails, bits of plastic from clothes tags (OK I still chew those).
I started buying perfumes I like and wearing them, even if I'm in my pyjamas 
You can have fun trying these out if you like things like that.
Activities like paint-by-numbers, or simple crafts. We are making Mario and Luigi out of toilet roll tubes at the moment.
For DS age 6 I have a few things for him:
Stretchy resistance band thing for his chair at the table
Various noisemaking toys, most of them toddler toys but I did find a great DJ car recently which seems less babyish and even has a headphones jack.
Pop its
Heatable wheat bag with lavender
Ice ready to go in the freezer (crunch it, melt it, smash it)
He climbs everything and bounces - we are looking into home equipment for this.
Playdoh.
