Water Squirting Nozzles

thingiverse

Various nozzles and mounting hardware for squirting water. I designed this system for use on an FRC robot, but it's wonderfully versatile and can be used anywhere you want. Good for about 25 feet with a ~0.5GPM (2lpm) pump. Includes nozzles ranging from 1.5mm to 4mm, several mounting plates, and a servo-mounted turret for motorized aiming. This system works with standard aquarium tubing (3/16"), or anything flexible and slightly smaller than 6mm (~1/4") ID. 1/4" tube is a bit loose and leaks water. Tubing should be press-fit, and if your printer's layer adhesion is pretty good you can pull the tubing off afterward without hurting the nozzle. A good pump to use is RobotGeek's Large Liquid Pump (https://www.robotgeek.com/large-liquid-pump), which is 0.5gpm and will shoot around 25 feet with the 2mm nozzle, and can really drench someone with the 3mm nozzle. Nozzles can be attached to a through-hole from the front using the mounts, or from the back using hose clamps. Use the large mount plate with wood screws to attach a nozzle to a board (1" thick works well). The nozzles should be printed tip down. Support is not needed other than a raft or brim to keep them from popping off. At some point I'll finish this up with more mounting hardware and more detailed instructions for the turret, but for now it's a Work in Progress.
