One of my storm door screen/glass pane clips broke so I created a replacement. I printed it in PLA as a test and then in PETG for weather resistance. Not sure how well the PLA would hold up but it's a quick print so you could try either one.

I printed it on its side for strength but it shouldn't need to withstand a great deal of force since it's one of 8 clips placed around the perimeter of the screen.
