A fire hydrant with a single 6" outlet. Hope to add the two 4" pumper outlets on the sides in the future. Currently in O scale only as I can't get it to print nicely in HO scale. If you would like that file as well, let me know and I'll add it.

Resolution:

Notes:
I used supports on the one in the photo. It may work without them. Sure would make it easier to clean up with out them.
