My storm door has a broken retainer clip that does not extend the entire height of the door. As a result, there's a drafty spot in the gap. This part fills that gap by extending the existing retainer clip.

I needed about 103mm to fill the gap.  This length can be configured in the model or physically cut to a smaller size.

Printed as shown in PETg, 0.3mm detail, 50% infill.
