I needed some reinforced hinge to hold a heavy stainless steel door from a bread trolley, and they are working pretty well ! Installed a pair since 2 months and no problem (with professional use moreover).

I was thinking of printing another pair to secure the door (would be 4 hinge total) but i won't as it's perfect like that. Really strong for plastic hinges !

And to finish, the hinges were making some little grinding noise with weight of door. I put some WD40 as i would do with metal ones, and perfect so far, never heard noise !! So PLA and WD40 are fully compatible :)
