Uni Kuru Toga Pencil Case

Everything you need for good design is a pencil and a piece of paper. So whenever I have an idea I do a lot of sketching. For this I love my Kuru Toga pencil and I keep it right next to my sketchbook, wherever I go. But it's tip is very sensitive and I wanted to keep it safe inside my backpack. My last sketchbook had a spiral binding and the pencil fit right into it so it was safe in there. But my new sketchbook's spiral binding has a smaller diameter so I needed some kind of case for my pencil. I wanted it to be as simple and small as possible, but still effective and practical. So I designed this case. It uses the pen's pusher to lock it in place.
I also made a version with a little hook so that the pencil can be attached to the spiral.
