TREX-compatible 6 inch end post cap

thingiverse

I designed a couple of TREX post end caps that broke, so I decided not to buy new ones and instead created my own replacement pieces. These are not exact replicas, but they're designed to fit standard 6-inch posts with an actual measurement of 5.5 inches. They should be easy to modify if you want to add solar or other lighting features. I made these pieces to print without supports, but you can use your favorite modeling app to combine the STL files and print them as solid pieces using supports when needed. This approach will waste some filament, but it might save you time in the long run. You should be able to scale up or down as needed to fit other common post sizes.
