This is my working pen I made. It prints in 3 peices that you will need to glue together. After you glue them all together, you need to take apart another pen, remove the long skinny peice that holds ink and is connected to the tip. Note not all pens are the same and you may need to take apart another one Slide that peice into the 3D Printed Pen in the right spot, then glue it in. If you want your name or something on it, you can message me and I can add it.
