I always lose my favorite pen, especially when I want to sketch something in my journal. Now, with this handy pen clip, you can secure 1 or 2 cylinder shaped writing devices to the cover of your favorite book. Just print and enjoy! If you like this project and wan't to learn more about making things with 3D printers, laser engravers and other cool maker-tech, check out my new book "The Makerspace Workbench" from Maker Media!
