I love Darth Vader's melted mask. My coworker brought in a Terminator pen cup and I wanted one, but not the Terminator one. At first I looked up Darth, but came across the melted mask and went with it instead. The Original Model is from a user named MadJack3dPrints on Thingiverse. I stuck a hole in it and have been using it for almost two years now!
