Description
I designed this full-size fire hydrant by request, from my cousin who wanted a fire hydrant for his dog. It has holes to use tent stakes to keep it secured to the ground as well as the center cap removable for storage for dog poop bags.
V5: Designed to print at 90% on a Prusa MK3/MK4 size printbed (210x220x250) in easy to assemble parts. Printed in PETG with easy snap-fit connections. The only parts that need glue are the nuts on the top and the 2 side caps. Based on an actual fire hydrant, stands 29.5 inches (750mm) tall. I have gone through many iterations to get the final result pictured.
UPDATE V6: Files have been rescaled to print at 100% and fit on MK4 build plate. I've included 3MF file with supports added where needed, which is minimal.
Approximate filament usage: 2kg
If you would like to check out my original design, which lacks most of the features of this one and is intended to be printed at 1:12 or 1:6 scale, you can find it for free here:
