Latch for 1960's era Arcadia brand screen door. Original was injection molded plastic with a shiny, polished finish. Arcadia no longer sells spare parts for these vintage doors, so homeowners need to scavenge or fabricate replacement parts.
I've printed these in "black, strong, and flexible", "gray robust", and "black detail." Black detail gives the best finish - the finished piece has a slightly matte finish compared with the original, but it's not disagreeably so. Black detail's underlying material is also black, so surface scratches won't expose white plastic as "black strong and flexible" will.
Photo shows original part, part printed in "grey robust", and part printed in "black detail."
This version is improved over my original design with slightly thicker walls for better strength.
