trailer plug back cover

i bought a replacement trailer plug for my car but it did not have back cover. so i made one. the plug is totally generic, 7-pin, it did not have a logo or a model name. look for sizes in attached media to see if it fits yours. it is a tight fit, intentionally. designed to be secured with 3 zip-ties (4x1 mm) instead of bolts.printed in tpu. no specific settings, use your own judgement. i printed mine with 2 walls / 15% gyroid, it was fine.
