Surface Pen (2017) Vertical Hinge Case

I wasn't happy with any available cases for the Microsoft Surface Pen (2017). I wanted something hard, low-profile, and that would snuggly fit my pen to protect it while in my bag.

This case is meant to be printed vertically. The hinges will initially make a small cracking sound as they are broken-in and they start to function.

EDIT 1: Added in the f3d file for anyone who wants to adjust the case for other things
