Pen of unknown usefulness

prusaprinters

<p>No idea what kind of pen this has become. It doesn't need a spring, a spare refill can be carried, or the refill can be hidden in the pen.Anyway, you can easily transport the pen. &nbsp;It is not yet optimal, because the two halves are still a bit too loosely connected. There is a hollow at the tip to put the finger in. That might help when writing.</p><p>Is the pen beautiful? I think not.<br>Is the pen ergonomic? Absolutely not.<br>Is the pen easy to print? I think so.<br>Who needs this pen? The whole world.</p>
