Outdoor faucet lock

My son and the neighbor kids are always playing with the water so I designed this lock.  It still possible to turn the water on in a slight stream but very minimal, which is good for being able to wash hands, but not turn the water on full blast creating a swimming pool in the front yard. 

printed in PETG, 4 walls, 20% infill  ... you may want to go a bit more walls/infill on the locking bar...
