This is an impressive project, and a testament to how accessible the prototyping process has become to laypeople. Despite having no background in industrial design nor CAD proficiency, this Canadian YouTuber managed to design and build a working prototype of a flying umbrella that follows the user.

(The first one, he freely admits, "exploded and destroyed a lot of the parts.")

After many months and a fair amount of setbacks, he does manage to get it to work:
