End cover for 5" PVC fence post used for Travel Trailer sewer hose storage

thingiverse

I needed a convenient spot to stash the heavy-duty sewer dump line for my travel trailer. However, the swivel fittings wouldn't fit snugly within the 4" trailer bumper (a concern shared by many who worry about moisture rusting out their bumpers). A 5" PVC fence post proved to be a great makeshift storage container above my bumper and behind the spare tire. I used sturdy pull straps to securely attach it to the bumper. Unfortunately, standard fence post covers wouldn't do as end caps for this DIY solution. That's why I designed and printed a custom-fit cover that fits seamlessly inside each end.
