I made these golf coasters as a gift for my brother. Each coaster is made up of 3 3D printed parts and a glass top (4inch glass coasters I bought on amazon). Everything dark green is one part (rough-and-bunker.stl). The blue component is water.stl, which fits on top of rough-and-bunker.stl. There are four different options for the green (green-rtft, green-mid, green-lt and green-rtrr). They are all the same green, but each has a different hole location.
For each of the coasters I superglued the parts together and used real sand for the bunker. To make the bunker I mixed water and craft glue (1:1), painted the watery glue into the bunker and then poured sand on top. I then turned the coaster over to dump out excess sand, and repeated the process if the bunker was fully covered with sand.
Also, to make the "golf ball" I snipped off a tiny piece of white filament and rolled between two pieces of sand paper until it was roughly spherical. The imperfection of the ball makes the game harder and thus more fun.
