Sink 3D Models: STL Holders, Strainers and Fittings

This collection gathers STL files for sink-area parts: sponge holders, strainers, drain plugs and small fittings. It is useful when a plastic part near the basin needs replacing or when a size has to match your own sink. Most of these models are small and print on a standard 3D printer. 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.

About the category

«Sink 3D Models: STL Holders, Strainers and Fittings»

The models fall into a few groups. Holders and caddies sit on or beside the basin and differ mainly in how they attach: a rim hook, a recess for a suction cup or a flat base. Strainers and drain inserts are shaped around a round opening, while plugs, overflow rings and siphon extensions follow a thread or a pipe diameter. Screws, hinges and similar hardware form a separate group, printed for cabinets and sink units rather than for parts that touch water.

Before printing, compare the author's dimensions with your own sink. For a strainer, the outer rim and the drain hole matter; for a threaded part, the nominal size and pitch; for a holder, the rim thickness and the space above the counter. Check the material and settings the author lists, because parts near hot water and detergents behave differently in different filaments. Photos of real prints show wall thickness and how the part was oriented, and the description usually states whether supports are needed.

If a search returns little, widen the wording. Sink parts are also listed as basin, washbasin, drain, plug, strainer, colander, caddy or organizer, and furniture fittings as confirmat, euro screw, cam lock or dowel. Combining a part name with a material, a thread size or a room such as kitchen or bathroom narrows the results. Related topics like under-sink storage, tap splash guards and cabinet hardware often lead to parts that belong to the same project.

FAQ

Frequently asked questions

What measurements matter for a sink strainer model?
The outer rim diameter and the size of the drain opening are the two that decide whether the part sits correctly. Compare them with the dimensions the author lists before printing.
Which filament is used for parts near water?
Authors often list PETG or ASA for wet areas, since PLA can soften with hot water. The model page usually names the material and settings that were used.
Can a printed screw replace a metal euro screw in a sink unit?
Printed threads carry less load than metal ones, so the answer depends on where the fitting sits. Check the stated diameter, pitch and length against the original part.
Do sink accessories need supports?
It depends on the overhangs and on how the author oriented the model. The description or the print photos usually show whether supports were used.
