Over the years we have had to replace/fix serveral of the window screens around our house. The retainer clips used are custom to our screen and neither the screen repair shops not I could find them anywhere. After reaching out to the manufacturer and not hearing back, I went ahead and designed replacements in OpenScad. They seem to be working.

In the picture the original is in the front. If you need them you will recognize them and here they are.

PETG may have been better to print for longevity, time will tell.
