The file 'Pipe Splitter And Adapter (from One ID 13mm Pipe To Five ID 4mm Pipes) 3D Printer Model' is (stl) file type, size is 474.5KB.
I needed to split the output of my submersible pump (ID13mm) to 5 4mm lines, which bring the water to 5 NFT tubes.
I designed this splitter/adapter so that there is no need for support/others. I printed it and it seems working well.
