A 3D printer forms a plastic mock-up of a mounting bracket used on the quad-band large aperture antenna system Nov. 19, 2020, on Ramstein Air Base, Germany. U.S. Air Force Airman 1st Class Trevor Zucker, 1st Combat Communications Squadron radio frequency transmissions technician, used his own time to create a 3D model of the bracket using a computer-assisted design program, and then used his personal 3D printer to produce a nylon filament proof-of-concept. Zucker created the part because of the challenges in obtaining replacement brackets, preventing the satellite communications system from becoming non-mission capable.
