i presented in front of 30+ people as well once and these are what helped me: 1. first thing i did was to let all of them know i stutter. and to basically bear with me since i tend to prolong my vowels and speak slowly to prevent that. did all of this with a smile and a laugh so its not that serious 2. used cue cards with bullet points and i did not have a set script. having a set script is just a way to make me mess up and i realized that i stutter less when i just speak freely. so i just practiced with cue cards and go through my materials afterwards to see what i missed/did wrong 3. i told my project partners that there might be a chance that i might shut down/struggle a lot. and told them to just let me continue for a bit and if it stays (or if i look like im panicking) to help me out on stage, or ask/signal if they should take over 4. using a lot of hand gestures help with my stutter i think warning the audience + having a backup plan in case something goes wrong helps a lot, since it lessens the pressure yk. and mastering your topic helps a lot as well. i hope this helps a bit and good luck!
