Print-in-place version of an any-direction putting practice hole.
My printer's unavailable right now, so I haven't tested it. Should work so far as I can tell. My concern is that the space between leaves may be too thin and not allow the ball to depress 2 at the same time.
If someone prints it, please share how it well it works. Given the steepness of the overhangs I recommend a high resolution, maybe 0.1 or 0.15mm.
