Summary

Cable holding clips for the old style galant with 5 straight legs - see reference picture, one to clip into the 10mm holes in the rear beam and the other to fit into the 10mm x 18mm holes in the side beams.
Remixed because the other ones were too loose for some reason.
For reference the 10mm ones are sized at 9.8mm on these, thats what the holes measure with the paint on, they are a light to firm fit, if they are really tight you may need to calibrate your extrusion multiplier.
I printed mine laying down at 0.2 layer height, with tree supports set to everywhere, then just picked the support out between the clip prongs.
