I needed a D9 for a game I was playing and couldn't find one, so I made this one. I also tried a single print version but this one prints 5X faster and I really liked the design challenge. Enjoy.

to assemble, screw one end cap on, slide the numbers pieces into the core, then screw the second cap on.

*BE WARNED*

The (7|8) and (3|4) pieces look very similar.

I suggest lining all the pieces up next to each other before sliding them into the core.
