Tape Measure Yagi Antenna

I modeled the couplers using Tinkercad, first by creating stand-ins for both the mast and the tape measure, then forming solids to join the two and grouping everything together. After making this long version I shortened it so the couplers could be closer together on the mast, and created a few versions for the end cap and driven element couplers. I printed the rainbow of parts on my Creality CR10s-pro using 20% infill. You can copy the design on Tinkercad or download my STL files.
