[3dprintscanner]

One site that I've found with a wide-ish breadth of events is https://evensi.com. They however seem to have too much choice and it's difficult to narrow down to a small relevant list of events. There sometimes are too many options that are vaguely interesting but too few that are genuinely engaging. Meetup works quite well in this respect as you can select your interests and it's not too difficult to scan the entire list if that doesn't offer a decent choice and it's certainly something Eventbrite lacks even though they have vast inventory (It's better designed for ticketing rather than discovery). I've tried to crack this and have put together a site to recommend you 5 interesting events each day over the next week. (Also all free entry with some food and or drink). Currently in fairly early stages and covers London. https://onlythebestevents.com
