With the release of the new Intuos Pro drawing tablet design came a redesign of the pen holder as well, and although it may look great, it's not as useful as the last one and even the last one wasn't amazing. One of my professors particularly has the problem that the pen always falls out of the holder when he's working by bumping into it (it's not difficult to do). After requesting one that came from an angle and held it more securely I created this design to accomplish just that.

When printing the model I filled it with sand in order for it to have weight without adding too much infill. The model can secured to your desk/tablet/computer by any other means like Velcro, glue, etc. as well.
