I didn&rsquo;t end up digitizing my own handwriting, but it pushed me toward a smaller idea: clamp a ballpoint pen to my 3D printer and let it write postcards for me.</p> <p>This post is the story of getting there, including the part where my printer almost drove the pen straight through the bed.</p>
