“I built this Bookshelf keychain for a Librarian friend of mine. She was looking for something to use as a demo object for her library’s new 3D printer. The keychain can be customized with any text you’d like, as well as having the text embossed or debossed. It’s a pretty quick print and is great for creating customized objects for groups of any size. Here’s a video showing the build. From drawing, to SketchUp prototype, to finished customizable OpenSCAD design: https://www.youtube.com/watch?v=D8lfMnmhgjc&feature=youtu.be”
