3D Models for 1-1/4 to 32 Fittings and Adapters
This collection gathers STL files for adapting 1-1/4-inch threads to 32 mm hose and pipe connections. It covers threaded reducers, hose tails, and pipe fittings. Use it when you need to compare options for a 3D printer to bridge a size or thread mismatch.

«3D Models for 1-1/4 to 32 Fittings and Adapters»
The models in this collection fall into a few practical groups: threaded adapters that change between BSP, NPT, or G threads; barbed couplers and hose tails that grip flexible tubing; and larger pipe fittings for pool, dust collection, or barrel connections. Some are simple single-piece reducers, while others combine a thread, a nut, and a hose barb in one body. The differences matter because thread form, pitch, and sealing method change how the part joins to the next component.
When choosing a model, read the author's page for the stated thread standard, nominal diameter, and whether the part uses a flat gasket, thread tape, or a clamped hose. Look at the wall thickness, the number of parts, and any assembly steps shown in the description. Photos of real prints can show whether the threads came out cleanly and how the adapter sits against the mating part.
To refine the search, try synonyms such as hose adapter, threaded reducer, barbed fitting, pipe coupler, and conversion adapter. Related terms include BSP, NPT, G thread, metric hose, and dust collection or pool plumbing. If the first results are too broad, add the connection type, the thread direction, or the material the author lists.
