3D printing1 partBeginner-friendlyNo supports
A reducer that joins a 100 mm and a 125 mm ventilation duct, with spigots on both ends and a 2.5 mm wall. Both ends go into the ducts: flexible aluminium duct slides over them, spiral duct takes them inside – for example behind a bathroom fan or cooker hood. Secure flexible duct with a hose clamp and seal with aluminium tape; PETG copes better with warm, moist air than PLA. Not for flue pipes of heaters or boilers.

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