Dark Helmet pen cup and koozie apparently

thingiverse

I discovered the Space_Balls_Helmet_Solid_V1 model created by Jace1969. I required a fresh pen holder, and modifying this model appeared to be the most efficient approach. I tampered with the original design and reduced it to 60% of its size. It took approximately 13 hours and still needs some sanding to smooth out a couple of rough areas from the supports, but otherwise, it's an excellent base to work with.
