X-Acto Hobby Knife Cap

I'm diving into the world of X-acto knife caps, and let me tell you, every single cap I've seen posted hasn't fit my knives right. That's why I came up with a solution: an o-ring to keep the tension on the cap just where it needs to be. So, here it is - a game-changer that requires one simple thing: an o-ring that fits perfectly. And the best part? You can use whatever you have on hand to design this beauty. Just find an o-ring that matches your needs, and voila! Your problem is solved.
