Replacement Above Ground Pool Top Cap (Vogue brand) Parts

One of my neighbors had an above-ground pool from a company by the name of Vogue – originally out of Canada. 

Over the years, the plastic parts have taken their fair share of the elements and abuse, and eventually flex tape, superglue and paint weren't enough to keep them going. 

Based on the original parts, I've designed functional replacement parts. Unfortunately I don't have the model number - but these appear to be the pool top caps for the posts. 

 As these are going to be parts in sunlight, I would suggest using something with a higher melting point and a bit of flex – PETG or ASA ideally.
