Garden Hose Spray Nozzle with Trigger (print-in-place)

thingiverse

Single-handled garden hose spray nozzle with trigger-operated water flow control, built as a functional prototype to test concepts. It performs well but has some minor leakage due to the absence of rubber seals. However, optimal print settings can minimize leaking significantly. Fitted for standard North American home garden hoses, be cautious when attaching the hose as it's easy to cross-thread. The trigger features no spring, instead relying on water pressure to generate resistance. This results in a loose button until the water is turned on. Work the button free after printing, as I intentionally left some extra space. Designed for face-down printing with the nozzle end on the print bed, ensure you rotate the STL file accordingly. Use external supports only to hold the handle and trigger in place during printing; internal supports are unnecessary. The handle size is slightly smaller than ideal, but this was a deliberate choice to save filament, as the prototype was intended for proof-of-concept purposes. The trigger travel distance also falls short of achieving smooth intermediate flow control, making it more of an "on" or "off" switch. A larger mechanism would have improved this, but would have required additional filament. This experiment suggests that designing a full-sized garden sprayer with good performance should be relatively straightforward. A practical design could also include interchangeable spray nozzles for added versatility.
