My new Lenovo Ideapad C340 didn't come with a pencil, so I had to buy one separately.
Unfortunately there is no way to attach it to the laptop, so I figured...Show more why not make an sd-card-slot-to-pencil-holder since I rarely use SD cards?
Designed to support 8,9mm diameter pens (I use the Dasaja Active Stylus Pen)
Is held in place by the sd card slot, pen fits snuggly.
On my laptop you can use it in both laptop and convertible mode and it doesn't het the table, it doesn't fall out when held upside down.
