If you don't already plan on doing this, disclosing your stutter at the beginning of the presentation could help a lot. I do it a lot with presentations, interviews, meeting new people, etc. It really helps ease my nerves because I'm not worried about hiding my stutter since the audience already knows. It can be something at the beginning like, "Hi, my name is _____. Just a heads up, I have a stutter, so please be patient as I may need extra time to get my words out." Also know that there's absolutely nothing wrong with stuttering during your presentation. People will understand and be patient, especially if you disclose at the beginning. As long as your speech is forward-moving, you're getting your message across! I wish you the best of luck.
