I created this for my small hydroponics setup as a splitter for the line coming from my submersible pump into three individual lines going to each planter. It is a very basic one to three splitter that should be useable with 1/4 inch ID hose. Added Edit: I noticed the connection was leaking on my setup so I added r2 with a better seal which is a bit larger with two lips. Printed with the larger side (three connections) facing down. Solid infill. On my printer I used no supports.
