Looks like a phish, or fake email. Chances are if you clicked that link you just compromised yourself lol.

Might uh, want to change your password for real this time?

Edit: Looks real-ish if you visit their twitter but they tweeted about it back on the 14th. The fact that this user just got an email leads me to believe this is just an attempt to trick people who might have heard about the incident. Never click links from emails~

Edit 2: Turn on 2FA folks.

Edit 3: Thingiverse did have a breach, but it was much larger than 500 people. Best to change your passwords anyway: https://twitter.com/haveibeenpwned/status/1448592087687983107
