2 piece cable grommet

I couldn't find the right wall grommet for my antenna cable so I made one. This is designed for a 3/4 inch (19mm) hole (approx) and RG-8X coax cable about 6.4 mm in diameter. outside diameter of the flange is 40 mm, 5 mm thick. Length is 30 mm. I printed mine from flexible filament. It is made to print in two halves and fit tight around the cable.
