2-piece grommet for starlink cable

thingiverse

This is a 2-piece passthrough grommet for a starlink or similar cable where you cannot take the ends off. Push the cable into the inner grommet, then add the outer grommet and turn it to fully cover the cable and hole. You'll probably want to seal it with some silicon sealer when you insert it into the wall. Files include both pieces individually and together. Fusion 360 source included for those who want to modify.
