One inlet at the bottom, two equal outlets branching symmetrically left and right – for splitting or merging lines.
Socket: the fitting slides over the pipe. Spigot: the fitting is inserted into the pipe or hose. Pipe end: the part is the pipe itself (outer diameter = pipe) – the sleeve fittings fit over it.
For a socket and a pipe end the pipe's outer diameter, for a spigot its inner diameter. Pipe presets fill in the right value automatically.
Diametral clearance between pipe and fitting. Larger = looser. The presets grow with the pipe diameter, a custom value stays fixed. Negative values give an interference fit.
How far the pipe goes into the socket, or the spigot into the pipe.
Socket: inner shoulder the pipe butts against. Spigot: outer collar that rests on the pipe end.
Sets the size of the stop: the shoulder narrows the bore to the pipe's inner diameter, the collar gets the pipe's outer diameter.

Angle of each outlet from the vertical axis; the outlets spread by twice this value. Up to 45° the part prints without supports.
Wall thickness of the printed part. Ideally a multiple of the line width (e.g. 0.4 mm nozzle: 1.6 / 2.0 / 2.4 mm).
Chamfer at the opening so the pipe slides in more easily. 0 = no chamfer.
For a socket (the part slides over the pipe) the pipe's outer diameter counts, for a spigot (the part goes into the pipe or hose) its inner diameter. Measure with calipers at several points and use the average – plastic pipes are often slightly oval.
Without calipers: measure the circumference with a tape measure or a strip of paper and divide by π (3.14). The pipe presets fill in standardised sizes such as HT or KG drain pipes automatically.
The fit is the diametral clearance: bore diameter minus pipe diameter. 0.4 mm clearance therefore means 0.2 mm of play on each side. The presets grow with the diameter because shrinkage, ovality and pipe tolerances increase on large pipes – “Normal fit” gives about 0.45 mm at Ø 50 and about 0.69 mm at Ø 110. “Normal fit” is a good start for well calibrated printers, “Tight fit” holds by itself, “Loose fit” compensates for less accurate printers and pipes. A custom value stays fixed.
If unsure, print a test ring first: choose a small insertion depth, print, try it on, adjust the fit. Undo and your browser's back button always take you back to earlier values.
The model already sits on the bed in a printable orientation. For watertight parts use several wall lines (wall thickness as a multiple of the line width) and 0.2 mm layers. For warm water or outdoor use, PETG or ASA work better than PLA.
