The inner tongue part inspired me to make it as the inner jaw of "Alien".

The pen in the video is unique, it has a 3D-printed spring inside the body, so it can be rotated open without a metal spring. It can be downloaded free at: [https://makerworld.com/en/models/12916](https://makerworld.com/en/models/12916)
