Tube Splitter STL Models for 3D Printing

This collection gathers 3D-printable splitters that divide one tube or filament path into two or more lines. It covers Y-shaped PTFE and Bowden splitters, multi-outlet hubs, and larger hose or irrigation adapters. If you run a 3D printer with a split feed path or need to branch tubing elsewhere, these STL files give you a starting point. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Tube Splitter STL Models for 3D Printing»

The models fall into a few groups. Filament-side splitters are usually small Y or three-way pieces sized around common PTFE tubing, and they often appear in multi-material or multi-spool feed setups. Hose and irrigation splitters are larger, with barbed or push-fit ends for soft tubing. Aquarium and lab versions sit in between, using narrow bores and simple branch geometry. Some listings pair a splitter with a cutter or another small tube tool.

When choosing a model, read the author's page for the tube size it is drawn around, the number of inlets and outlets, and whether the bore stays smooth through the junction. Check whether the part is one piece or several, how the branches are oriented, and whether the author shows a print with supports or without them. Material and settings matter too: a filament splitter sees repeated motion and friction, while a hose splitter mostly sees pressure and water.

To widen the search, try the terms people use for the same idea: Y-splitter, three-way splitter, branch connector, manifold, or distributor. Adding the tube size, the tube material, or the machine family narrows results quickly. Related topics such as tube connectors, couplers, adapters, and fittings often surface models that do the same job in a different shape.

FAQ

Questions fréquentes

What is a tube splitter used for in 3D printing?
It branches one filament or tubing path into two or more. Common uses are feeding a single hotend from several spools or dividing a PTFE line between tools.
How do I pick the right size?
Match the model's stated inner and outer tube diameter to the tubing you have. The author's page usually lists the bore and the tube size the part was drawn around.
Do these parts need supports?
It depends on the branch angle and how the model is oriented. Many are designed to print flat, but check the author's photos and notes before slicing.
Which material works for a splitter?
For filament paths, a stiff filament that holds a smooth bore is typical; for water lines, the choice depends on pressure and temperature. The author's page often names a material and settings.
