This is a replacement headlight shell for a 1983 Honda ATC185S and will fit other models with a rectangular headlight housing. I printed using ESun PLA + (plus) and painted with Rustoleum Satin Poppy Red (paint and primer in one, specifically stated bonds to plastic).

All print settings are shown in the attached screenshots. Using the speeds and layers shown, it is a 22 hour print.

Depending on your printer you may need to babysit it as it makes the closed portion of the shell (top side as it sits on the bed). I had some light curling at the back edge due to the overhang angle. There wasn't enough support between layers if I had to guess. I would pat it down with a putty knife and it worked OK.
