Pen Holder for Quick Change Tool

Summary I made a pen holder for my own quick tool change system. The design of umer3d was the best I could find but it had the same problem as most other designs here: they are made for too small pens!!! Seriously none of them can hold a Sharpie. Nevermind the explanation and the tool for pen plotting are really awesome and helped me a lot!!! So I scaled the design up a little, made the whole base smaler ( I don´t see why it had to be that big) and added the base of my quick tool design for i3 like printers. If you enjoy this it would be great if you could give me feedback in the comments, a like and post a make if you did this.
