Give worn, cracked, or missing railing post skirts a second life with this 3D printable snap-fit replacement cover. 

Avoid replacing an entire railing section for one broken trim piece: A practical repair print for worn, cracked, discolored, or missing vinyl post skirts.

Designed for 2" square posts with a 4.25" x 4.25" base footprint.

Designed after an original vinyl railing base trim, this model installs around an existing square post without needing to remove the railing.

The design uses a 2-piece interlocking system that assembles around the post and creates a clean finished appearance similar to factory parts. Ideal for replacing discontinued or hard-to-find post skirts on decks, patios, porches, or fences.
