I pressed my face too hard against it earlier today, and the eyecup came off stuck to my face!
BTW: The eyecup has two positions. The lower or "locked" position can be used if the 46mm filter is not required. Give it a try. We are also in the process of designing a couple of different eyecups. Sorry, no delivery dates at the moment. We will contact all DP4-EVF owners once they are available.
