Lawn Spot Sprinkler

This is a small lawn sprinkler for covering areas up to 6 meters in diameter depending upon your water pressure. It is based off of a metal sprinkler design from the 1800's which has pretty even coverage and can work even at low pressures. There are no moving parts. The water enters the sprinkler from the side which causes it to spin out of the top.

The housing part (snail shaped) should be printed with the smaller hole down to the bed. The insert piece (cap) should be printed with the coin slot down to the bed. Once printed, spread vaseline generously on the threads and the cap should spin into the housing quite easily with a larger coin until a seal is made. You will need to add a standard hose washer to prevent leaks and it should work with the North American standard hose thread.

It doesn't have to be printed in orange PLA like I did but it makes it easier to find in the grass.
