Nozzle Pen Body

<p>In the words of Hannibal Smith, I love it when a plan comes together. I had been turning the nozzle design from the <a href="https://www.prusaprinters.org/prints/124472-nozzle-zip-tag">nozzle zip pull</a> into a pencil topper and I realized that with just a few little tweaks this could be a pen body. I broke out the gold PLA and got to it. The video came out really well, the stem of the pen appearing almost to grow like magic from the base. Then I happened to notice that my Galaxy Black Prusament was running low, but I reckoned that there was just enough to do the handle of the pen. So a quick reset and off we go again. Towards the end I didn't think there was going to be quite enough, the filament spool holder kept sliding around on the bench top, but it got there with a couple of metres to spare! The gold filament really contrasted nicely with the galaxy black. I can't say its the most comfortable pen to write with, but a really pleasing outcome for something that I just started on the off chance.</p><figure class="media"><oembed url="https://youtu.be/Dru0brN9mS4"></oembed></figure><p>Its another OpenSCAD design, again its a parametric design so it should be straight-forward to tweak it for your ball-point refills. I found that needed to allow about 0.5mm clearance around the shaft of the tip to allow the refill to clip into place snugly.</p><p>Hopefully the design parameters are reasonably intelligible, these are:</p><ul><li><i>id</i> - Inner diameter of handle of pen</li><li><i>sd </i>- Outer diameter of handle of pen</li><li><i>sl </i>- length of pen body</li><li><i>td </i>- tip shaft diameter</li></ul>
