Firehydrant Dog Poop Bag Dispenser - No Supports! (Screw down -or- Connect Leash -or- Print for Pockets)

Multiple versions!! There is a standard version that will easily fit in pockets or hip sack. There is a version that the fire hydrant has a connector ring to connect to a leash two different ways, hook shown for scale) etc. Finally, there is a cap with counter sunk holes for (2) - #8 screws. (Screws need to be at least 20mm/.75" in length minimum) allowing the fire hydrant to be installed at a stationary location. I designed this to be easily printed. No supports required. The version shown in the image is the standard version.

.2mm tolerance on the thread profile, so it's forgiving but tightens correctly.
