Dan’s phone has an awkward design with the microphone on the bottom and speaker on the back. A holder with appropriately placed openings for a Samsung Note 4 was impossible to find, even on Amazon. So Dan printed one.
Dan used OnShape to CAD the holder. Of course, there is carbon fiber reinforcement since it was printed on a Mark One.
The phone holder is shaped to direct the sound towards Dan’s desk, sparing the rest of the office from Eye of the Tiger. The cutout for the microphone allows Dan to use it as a speakerphone, too.
