Vòi tưới cây cho sân vườn

This is my very first attempt at building a water sprinkler, so if you have any suggestions for improvements, I would be grateful.

It has 3 x 12 holes (minus one) at angle 30, 45 and 60

An anchor can be attached to the bottom of the sprinkler

The connector is Gardena compatible (among others)

Infill 15%, well don't have to be water tight :-) , the sprinkler house seems to become filled with water and makes it heavy so you may not have to use the anchor.

Attaching an O-Ring for the connector and a flat O-ring as well if you feel you need one, and can print FLEX-material
