Drain pipe reducer 40 to 32 mm: preview of the model

Drain pipe reducer 40 to 32 mm

3D printing1 partBeginner-friendlyNo supports

A reducer for unpressurised drain pipes: a 32 mm pipe goes into its socket, and its 40 mm spigot goes into a 40 mm drain socket. A typical use is the 32 mm outlet of a washbasin trap on a 40 mm drain, for example in a workshop or garden shed, or when an old part no longer matches. Fit it with the socket facing up so the water runs from the narrow pipe into the wide one; PETG copes better with warm water than PLA.

Tip: Print standing as shown, no supports needed. With 3–4 walls (perimeters) it becomes watertight; a hose clamp holds hoses on the barbs.
