Tube Connector 3D Models and STL Files

This collection gathers 3D-printable tube connectors used in filament paths, frame joints, and hose adapters. It helps you find STL files for replacing a worn fitting or building a custom connection. Check dimensions and thread type before printing. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness.

Come è composta questa raccolta

Polyzon compone questa raccolta a partire dai risultati di ricerca dei siti collegati. I doppioni e i modelli senza anteprima vengono rimossi, le corrispondenze deboli finiscono in fondo e il resto mantiene l’ordine dei risultati. I modelli appartengono ai rispettivi autori: verifica le condizioni sulla pagina di ciascun modello.

Informazioni sulla categoria

«Tube Connector 3D Models and STL Files»

The collection includes several families: PTFE and Bowden connectors for filament guides, push-fit pneumatic fittings, replacement or reinforcement pieces for printer feed paths, and larger frame, pipe, or hose connectors. Some are small single parts, while others include holders, clips, or multi-part kits. A generator-style model can create a connector around dimensions you enter.

When choosing, open the author's model page and check the tube outer diameter, thread size and pitch, and whether the part is meant for a straight or angled run. Look at the number of parts, assembly steps, and whether supports are needed. The author's listed material and slicer settings give a starting point; photos of real prints show how the threads and gripping features turned out.

To refine a search, try terms such as pneumatic fitting, push-fit adapter, Bowden coupler, filament guide, hose joiner, or frame connector. Add the tube size or thread standard if you know it, and pair the term with the printer or machine family you are working on. Related searches include cable clips, tube holders, and replacement feed parts.

FAQ

Domande frequenti

What is a PTFE tube connector used for?
It joins or anchors a PTFE tube in a filament path, often at the extruder or a reverse Bowden run. Some versions also hold the tube at an angle or add strain relief.
How do I choose the right thread and tube size?
Measure the tube outer diameter and the thread on the existing fitting, then compare those values with the dimensions on the model page. Thread pitch and the length of the threaded section matter as much as the nominal size.
Can I print these connectors in different materials?
The author's page may list a material and settings. For small threaded parts, layer height and orientation affect how the threads form, so check photos of printed examples.
What if I need a connector for a square frame or a hose?
Search for frame connector, pipe joiner, or hose adapter instead of filament-path terms. Those models use different geometry and often include multiple parts or inserts.
