I had a couple TREX post end caps break, so rather than buy replacements, I decided to design replacement pieces. These are not exact replicas, but are designed to fit standard 6 inch (5.5 inch actual measurement) posts. These should be easy to modify to add solar or other lighting, if you wish.
I designed these to be printed without supports, but you can combine the stl files using your favorite modeling app, and print as solid pieces, using supports as needed. This will result in some wasted filament, but can save you time in the end.
You should be able to scale up or down as needed to fit other common post sizes.
4-11-2020: consolidated other TREX-compatible items (6 inch base and small support base) pieces as well. Small support bases are thin, and really work best printed out of nylon, ABS, or TPU (my favorite).
The 6 inch base is provided in 3 models:
1) whole piece - best if printing pieces to install when the uprights are being installed.
2) base with single 0.1mm slit and holes for 1/8 inch dowel. This is for replacing a broken trim piece, and works best with flexible filament such as TPU so you can wrap it around the base and then use urethane or other flexible glue to keep the dowel in place.
3) half pieces with holes for 1/8 inch dowels on both sides. This is best if you are using more rigid filament that doesn't flex enough to wrap #2 around the base.
A printable 1/8 inch dowel is also provided in case you don't have wooden dowels, and/or want to print everything yourself.
