Golf Putting Ring with Spacers

Dial-in your putting game with this modular practice putting ring designed to turn any room into a focused training space. The cup ring is built to regulation size and cleanly captures successful putts. Whether you’re working on short pressure putts or refining distance control, this design keeps practice efficient, engaging, and repeatable.

What sets this model apart is its fully modular difficulty system. In addition to the standard hole size, it includes three interchangeable reduction rings that progressively shrink the target to sharpen accuracy and confidence. Each ring is clearly labelled for quick identification in both imperial and metric units, so you can instantly adjust your training level. Print it, swap the rings, and level up your putting precision—one roll at a time.
