Created these for our Region President, Dan Sobczyk.
They look great and I will add a photo of them installed when that happens.
They are printed in 2 parts with the outer ring including the tabs to mount it to the lamp frame.
The 2 samples provided indicated that AMC used different colors which triggered me to print in both black and silver.
Here are both the new parts and originals:
These were printed in PETG but ABS would be a good choice too. PLA would melt in a typical interior on a summer day.
Lenses are printed with supports. Mounting Ring is printed face down / tabs up with no supports.
The model can be found here:
