You should be able to just put your hand in front of the nozzle and see if the flow is moving.Thanks!
Water comes out. I'm not sure if it's really random, but I can direct the flow, which is nice. I'd have to wait for something else on it to see how random it is. I'll probably print a new one at a higher quality for the final one though.
RFG nozzles are super finicky with flow rates. Too low or high and the flow stays in one stream.
I would love to have a 3d printer and time to learn it. I'd print so many things..
