12 Rules for Life: Rule 9 Tubular Blank Key (Chicago Ace/Ace II) Regular.

thingiverse

This is a custom key based on Chicago Ace AceII tubular locks (standard size). You can use my Dremel attachment to trim the key. The key features Rule 9: Assume that the person you're speaking with might possess knowledge you lack, abbreviated on one side and a listening icon on the other. The key functioned seamlessly on my tubular lock.
