Lawn Sprinkler Mini

thingiverse

This is a mini version of my lawn sprinkler. A helical insert is required to get the water spinning to allow it to be thrown evenly. https://www.thingiverse.com/thing:4400636 Print the housing with the exit hole down with no supports. Print the insert with the coin slot down with no supports. Install the insert with a little bit of vaseline to ensure a good seal. Install a standard rubber washer and use a landscape fabric staple to hold the sprinkler in place. I placed containers at 1 foot intervals radiating out from the center to measure how even the water is spread and it is very even over its entire coverage. I used PLA but it may break down quickly with use although I used my larger sprinkler all summer and it is still in good shape.
