These versions have a slot in them, so they can be installed over the existing harness wire. Once pressed into their clips, the slot is closed tight by the clip and the grommets/wires are every bit as secure as the originals. The fronts work in the plastic clip with part number 999.651.202.40, which fits most 944's, some 928's and most '84-'89 3.2 Carreras. The rears are designed around the rear 944 clip, but also fits any car with a 10mm clip opening.
Must be printed in TPU (rubbery plastic). On my Bambu Lab X1C printer, I print these at .24 layer height with 6 lines per wall, which allows it to print without supports. (Don't print it upside down, the groove is designed to print without supports only when standing upright as modeled.)
