G1 1/4 Adapter 3D Models and STL Files
This collection gathers STL files for adapters that bridge different thread standards, hose connectors, filament spools, bit drivers and camera mounts. It helps you find a starting point for 3D printing when a direct connection between two parts is missing. Each listing points to the author's page, where the actual dimensions and print details are described. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.
How this collection is put together
Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

The results cover several families of parts. Threaded plumbing adapters connect different hose, tap and tank fittings, often with inner or outer threads. Filament spool adapters let a smaller or refill spool fit a larger holder or a dryer. Bit and socket adapters change between square and hex drives, while camera and tripod mounts use a common small screw. Pump and irrigation fittings form another group, including splitter and drip connections.
When choosing a model, check the thread type and direction, the measured diameter and pitch, and whether the author shows a seal or gasket. Look at the number of parts, how they join, and whether supports are needed. The material and settings listed by the author matter for parts under pressure or repeated use. Photos of real prints can show how well the threads and sealing surfaces came out.
To narrow the search, try synonyms for the connection you need, such as hose adapter, thread reducer, spool holder adapter, bit holder or tripod mount. Related terms include plumbing fitting, garden hose connector, filament spool converter, socket adapter and camera screw. Combining a thread standard with the part type usually gives a shorter list than a single broad word.
