Star Trek : The Next Generation Comm badge - refined
I actually took a version that was derivative of this one from Cults3d and tweaked the oval. This one has essentially a solid oval that I created, and the delta is split into the frame and main portions, taken from the cults version. I find it best to print the oval at a 45 degree angle using normal supports in Cura. and the delta pieces face down on the print bed.
