Cap for Maker Knife

I have a [MakerKnife](https://giaco.com/products/maker-knife). I made a little cap that snaps on the end of it to provide some extra assurance that the sharp blade wasn't going to come out unexpectedly while the knife was in my pocket or banging around at the bottom of a bag.

The inside of the cap has some features to grab the sides of the knife and click into place, and a small ridge to keep the blade fully retracted. There is a little tab on the end for clicking the cap on and off with your thumb or finger.

You can see the one in the pictures is well-worn. I've been using it for more than a year.
