Description

It had been a while since I last used SketchUp when I created this model of one of my technical pens. (I also wanted to do more pen & ink drawing at that time, too.) I didn’t have any plug-ins for SketchUp that would help draw the threads, so I created simplified threads where needed. Even so, I’m confident about the accuracy of the rest of the model because I used a digital caliper and micrometer to measure the dimensions of each part.
