Realistic Golf Putting Hole With Flag

I designed this practice putting hole to look as realistic as possible so you feel like you're on a real putting green when you're practicing at home. The curves are flowing rather than sharp and geometric, mimicking the gentle slopes of actual golf greens. The flag is smoothly contoured to look like it is blowing in the wind. The white cup liner provides both a nice aesthetic and a satisfying clink when the ball goes in the hole. 

Functionally, the hole is extremely satisfying to use. The slope is very gradual so the ball doesn't need much speed to make it up into the hole. The gentle curves of the edges give very slight assistance to putts along the edge, but proper speed and accuracy are still required to hole putts consistently. It closely matches the difficulty level of a real golf hole. The hole is slightly smaller than a real hole, so if anything it is a touch more challenging. It can be used with or without the cup/flag, as seen in the included gif. 

As for printing, the main hole and cup both print at a layer height of .15 to minimize the stair stepping effect while keeping a reasonable overall print time. All objects shown are included in the one print profile each on their own plate. The flag can be printed in single or multi color. I will warn that the multi color flag uses a lot of filament if you don't have an h2c. Even with the h2c, the prime tower is heavier than the flag itself on default settings. I have lowered the prime volumes without any noticeable quality loss in this print profile. A single color flag will print with an almost flawless surface, so that is definitely a simpler choice.
