This will fit snugly into a hole drilled with a ¾" spade bit with a bit of overlap you can use to glue/add a grommet for a good seal. The hole is designed for the Starlink dishy→router cable and works nicely for those of us who didn't want to buy a routing kit. The stickouts will bend in a bit and grab (not pinch) the cable and offer a bit of security i.e. the cable shouldn't slide in and out.
Print 2, one for the outside, one for the inside. I used Prusament PETG and it works nicely.
