Alright printer was backed up finishing other projects but finally had time to print a full prototype for the lower cover, fitment is looking good, just need to make one more slight tweak and finalize the best way to print such a large piece.
Somewhat off topic but here is some of the other stuff I have been designing and printing:
Replacement fender grommets for headlight wiring, same style as OE.
Replicated all of the plastic pieces on the Fender mirror reproductions I had, and designed some TPU gaskets to hold new mirrors in place. The housings are powder coated black chrome.
