Monitor Mounted Pen Holder

This is a monitor mounted pen holder. It requires no adhesives to assemble. All of the parts simply fit together. The clamp and the pen holder can be friction fit together. Then screw the bolt through the backside of the clamp. Then attach the disk to the bolt inside the clamp. Place the bottom of your monitor in the clamp and tighten the bolt until the clamp holds on to the monitor. This pen holder can hold most pens up to 150mm in length and up to 19mm in diameter. The pictures show the pen holder with a cheap BIC pen but it also works with other pens i have tried such as a Big Idea Design TI Arto EDC.
