Pentopper bottle with handle Free 3D print model

Bic pens are universal. Nearly 150 million of them are sold each year in the US alone. But what if you want to hang them next to a noticeboard? How often have you seen one of these pens with a piece of string wrapped untidily around it, secured by a mess of tape?

Well, no longer. It took me just 10 minutes to create this pen topper using Autodesk 123D Design, and a further 18 minutes to print it. And you can read how to design one yourself even if you have no knowledge of CAD design:
