If you do like to write or draw with extremely fat pen, and want to be able to take your pen with you, than print it.
It's an extremely fat dip pen, with detachable nib clip, which can be stored inside the pen stem, protecting your precious nib.
There are two variations of the stem: one piece and split in two halves. The latter is much easier to print. Keep fine line height for all threaded parts (0.15-0.2 mm). You may need to print with outer perimeters first option.
I've found no reliable way to print the nib clip. I recommend to cut a strip about 15 mm wide from some soft/rubbery material, like silicone, (I've got mine from silicone tubing) roll it to… uhhh… the roll with diameter about 6 mm and push it into the nib hole. You'll get nice tachikawa-style clip, which will last for long.
There are a lots of options: eraser, cork, piece of soft wood, earbuds...
