This is the front turn signal lens for my 1948 Plymouth Coupe. My "Hot Rod" is built on a 1969 Camaro frame and never had that lens installed, so now it does! I'm not sure if anyone can use this, but here it is anyway. It is about 3" in diameter and could be scaled for other uses I guess.
The photo of it printed in white was my first version printed in draft mode just to check fitment. I made a few changes for V2 and will upload a final print photo when it's done.

Final print was done with eSun translucent orange PETG. I had to do a few trials using the PETG to get it to adhere to the bed. Finally using blue painters tape and slowing the print speed down I got it to work. I used a .12 layer height with the PETG, but I got a better print with the PLA at .3. I also used a raft to get better plate adhesion for the first layer and it worked perfect. The inside of the lens I tried to make with a pattern so it would help light refraction, but that was a fail. I will repair that and re-upload the design as V4
