Retractable Pen Machining Project.

Once I saw this video, I knew I had to try to make my own using machine tools. Here’s my OnShape model with some drawings.  It uses Pilot G2 cartridges.  They’re my favorite and readily available. You’ll need some aircraft length drills and a 3/8 – 24 tap to make the body sections.
