This is a replacement for a sliding screen door handle which broke.  I based the general shape on the original part, but made the back edge sit closer to the metal and added a rounded extension to form an easy-to-use handle.

I used snug supports and variable layer height (0.4mm nozzle).  Printed in PLA since that's what I had handy and I was replacing the inside handle.  It will get some sunlight so will have to see how it holds up.

I think different door manufacturers use similar parts with varying dimensions and hole spacings, so I've included the SCAD file for tailoring to different configurations.
