3D Models of Splitters and Y-Connectors

This collection gathers STL files for splitters: Y-shaped connectors for tubes, multi-way air and fluid dividers, and a few workshop or game-inspired shapes. It helps you find a starting point for 3D printing a part that divides one line into two or more paths. Check the dimensions and fittings listed by each author before printing. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Models of Splitters and Y-Connectors»

Some models are made for filament paths and PTFE tubing, with two or more outlets and often a push-fit or threaded connection. Others divide air or liquid lines, such as aquarium air tubing, pneumatic hoses, or washer fluid. Multi-way and quick-lock versions trade compact size for more branches, while workshop and game-inspired splitters follow a different logic entirely.

On the author's model page, check the tube or hose diameter, thread standard, and number of branches. Look at whether the part needs supports, how many pieces it includes, and whether assembly uses glue, screws, or press fits. The material and settings the author lists matter for parts that carry air, water, or filament, and photos of real prints show how the channels and connectors come out.

Try synonyms such as Y-connector, tube divider, manifold, or multi-way adapter, and add the tube size or thread type you need. Related searches include PTFE tubing, Bowden tube, pneumatic fitting, aquarium air line, and hose quick-connect. If you are looking for a specific printer setup, combine the splitter term with the filament path or multi-spool routing wording, but verify the dimensions on the model page.

FAQ

Preguntas frecuentes

What is a Y-splitter used for in 3D printing?
It divides one filament or PTFE tube path into two, often to connect multiple spools or an external spool to a printer's feed system. Check the author's dimensions and connector type before printing.
Do splitter models need supports?
It depends on the shape and orientation. Many Y-splitters print as a single piece with overhangs, while some are split into halves or use threaded inserts. The model page usually states the intended orientation and support needs.
How do I choose the right tube or hose size?
Measure the inner or outer diameter of your tubing and match it to the dimensions in the model description. Threaded versions require the correct thread standard, such as G1/8 or G3/4, if that is what your fitting uses.
Can a splitter be used for air or water lines?
Some models are made for air, aquarium tubing, or washer fluid, but the author's page should list the intended medium and connection method. For any line under pressure, check the wall thickness and fitting type before printing.
