This is Communicator Badge as seen on Star Trek: The Next Generation. I designed it based on the official resin model. The new "thick" version is slightly redesigned to be more accurate to the real prop. I find this to be an excellent calibration object because it is small, prints quickly, but has a unique shape that is tricky to print if the machine is not calibrated properly.Paint the round part gold, the delta silver, and outline the edges of the delta in black.Glue a pin or velcro to the back and you've got a great addition to a uniform or just something to wear to show you're a Trekkie.
