Bullet pencil

My attempt at a 3D printed bullet pencil. It printed fairly well on my Ender 3, after some tuning of the tolerances. I'm not sure how well this will translate to other machines.

In terms of practicality, it has survived a couple of days in my pocket so far. It also makes a very satisfying "pop" when I open it.

The original OnShape design is here:
