One of my friends snapped one of his old Trex post caps and couldn’t find the same style anywhere. Since the original design seems to be long discontinued, I took measurements from the original and modeled a replacement.

The cap has the same slim, low‑profile look as the original and fits with a simple press‑fit. No hardware needed — just line it up and press it into place.

Printing Details

• Printed in ABS for outdoor durability
• Upside down on the build plate
• No supports needed
• 0.2 mm layers, ~30–40% infill

It’s a straightforward print and should drop right onto the post with a snug, clean fit. Great for anyone trying to keep an older Trex setup looking consistent without replacing the whole post.
