Ideally you should text him that same day (unless it's super late, in which case text the next morning)
"John, nice meeting you today! :)
this sets the premise for conversation and makes any later texts less awkward.
if you're already passed the day of and the day after, then just wait for 3 days after you met and if he hasn't text you by then text him.
mention his name, your name (in case he forgot), and focus on finding out his schedule so you two can set up a time to meet.0THIS IS NOT RELEVANT ANYMORE

I think if it feels like you want to message him, just message him. there's no rules when it comes to this stuff, just go with your gut. Say hey, remind him who you are, and ask if he wants to meet up :)0THIS IS NOT RELEVANT ANYMORE
