Open 3D fountain pen cigar shape barrel cap

thingiverse

Included are printable STL files starting with "Open3D fountain pen" for: 1. standard size barrel/body which can accommodate two short international ink cartridges or a standard converter (one in use, one for spare), 2. mini size barrel/body which can contain one short international ink cartridge (for those who like short pens), 3. mini size barrel/body with threads on the back to screw the cap firmly on when posting cap, and 4. the cap itself. For convenience, I'm also including Zoidberg38's pen section. Hargo's Kaweco section variation would likely fit; however, I haven't tried it. Files starting with "working" were my working files used to create the shapes and join them together. Feel free to use them to make your own pen variation. The OpenScad files were used to create elliptical streamlined shapes. The threads were cut out from Zoidberg38's designs and pasted onto the shapes using Microsoft's 3D builder. With Microsoft's 3D Builder, it was quite easy to load an object and attach it to the pen. Then just merge the objects together and print it. For the business end of the writing components, I used Lamy nib/feed from Aliexpress, costing about SGD $5 for a set of five feeds and nibs. The straw is required as an ink barrier because PLA seems to be a bit porous. When ink touches it, it soaks through and stains the material.
