Turn your backyard into a golf course with this quick and easy print! This is a regulation size golf cup that features drainage holes to keep your balls clean and is strengthened for 3d printing. Recommended to be printed in ABS or other outdoor-friendly material for longevity, but PLA will work just fine as well. Easy to install: Just dig a hole, place your cup, and enter your private putting green. The center of the cup features a ¼ inch hole that is perfect for a bike safety flag (found on Amazon at: https://a.co/d/7uA0ord ), a cheap alternative to overpriced golf flags so you can spend more on your clubs and less on your course. If you print it, be sure to send me a picture of your backyard greens!
