Antenna Topper

This goes on the top of antennas for car CB, ham & AM/FM radios.  Helps with spotting a car in a parking lot and safety if you need to remove the antenna.  I printed this with 0.8mm perimeters and 10% infill to make them as light as possible and in PETG so they can handle the sun better.  Layer height it 0.2mm  They really don't need to be strong.  Pick a sleeve based on the dimensions of your antenna.  No supports needed.  The two sleeve parts enclose the antenna and the antenna topper screws around the sleeves.  Please see pictures for more information.  I printed the parts in the orientation in 3MF file.  It worked well for me, but feel free to try different orientations.
