This print file offers important visual advantages over the high-density styrofoam component that comes with the Voyager SCI Kit (VSK) and the Magellan SCI Kit (MSK). It is also the correct scale for the free Cassini model, but the feedcone in the center does not replicate Cassini's more complex feed array.

The main reflector is paraboidal, which is more accurate than the spheroidal shape of the styrofoam HGA. It also has a more accurate thickness, which is especially visible at the edge of the dish. Integrated into one printed piece are: six-strut tripod, subreflector, feedcone, waveguide, and low-gain antenna. The main reflector has a hole for the sun sensor assembly.

For printing using FDM, this component requires dual extruders; soluble support material is required. White ABS plastic and soluble HIPS plastic (for support) are recommended.
