This is a hollow version. Very accurate representation. It is 3.0 inches in diameter. There is a very small hole at the bottom. Can be easily filled with epoxy and painted over white. It's white there because there is snow there. View in 3D and hold the up/down arrows and you'll see the hole come around. View my store for a solid and smaller version.
I just updated the design to be a bit thicker to allow the printing process to be more successful. Apologies to those who tried to print this recently and it failed. It did print before, but it was difficult to get finished, so I've had to increase the wall thickness. Again, sorry for the inconvenience.
