This is a simple 3D-printed end cap designed to cover the ends of the wooden rods and give the shelf a cleaner, more finished look—especially helpful if your cuts aren’t perfectly straight (you’re not alone 😉).

The cap is designed for a snug friction fit on Ø16 mm rods. If the fit feels too tight, you can easily adjust the overall model scale by 1–2% in your slicer for easier installation.

A small addition that makes a big difference in the final appearance of the shelf.
