I made this for the simple reason that cartridges for Parker Vectors are super expensive in my place. But you can make use of this if you lost your cartridge too, or you can't find a converter that fits into the pen. This design makes use of clear PLA as a substitute for the cloudy plastic commonly used in pen cartridges.
I have included **two models**: one in **standard** and one in **large**. The standard model have almost the same length of Parker cartridges. And the large, is simply a stretched out version of the standard with additional 22mm. in length and holds more ink. One can use **a syringe** to load ink into this cartridge.
You can also make your own design as the only important parts are the cartridge nipple size which has an **inner diameter of ⌀3.5mm.** and the pen shaft which has an **inner diameter of ⌀7.0mm.**
I have also included my print settings below for those having trouble printing it.
