This is to replace broken plastic end caps on the tops of the lower two sections of a three-section loft ladder.
The loft ladder is quite old and the manufacturers label has long since gone.
I think it was made by ABRU. There are four clip-on plastic caps covering the sharp ends of the aluminium sections.
(The top section also has plastic caps, they are slightly longer than the ones for the lower sections. I need to make two more to fit that later.)
I made the cap look similar to the original apart from increasing the thickness to improve strength.
I used PETG for durability and flexibility.
