Mine are:
Rubbing my hands together is probably my main one.
I also will bite nails/fingers and put certain things in my mouth like hoodie cords.
I'm also very fidgety and will mess with whatevers Infront of me and jig my leg but I feel like this might be more ADHD related than a stim.
Have you tried Chewbuddy, assuming you are in the UK, it is very good.
