Test Tube 3D Models: Racks, Stands and Vases

Test tubes appear in 3D printing in two roles: as the object being held, and as the container a printed shape is built around. This collection gathers racks, stands, holders and vases made for common tube diameters. Most files are plain STL meshes, so the tube size matters more than the shape. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Test Tube 3D Models: Racks, Stands and Vases»

Racks range from single-piece benches that hold a few tubes to modular frames that clip together into longer rows. Foldable stands trade rigidity for storage, while vase-style holders use the tube as a water reservoir inside a printed shell. Some designs follow a named laboratory standard, others are built around a measured diameter, and a few are aimed at a specific job such as holding spices or an aquarium test kit.

Before printing, compare the tube diameter and length given on the model page with the tubes you have, since a fraction of a millimetre decides whether a tube slides in or jams. Check how many parts the model has, whether they are joined with glue or screws, and whether the author shows a photo of a finished print. For vase designs, look at wall thickness and whether the file is meant as a single wall or a solid shell; for racks, look at how the base sits on the bed.

Search terms shift with the use: rack, holder, stand, base, tray and insert describe similar parts, and adding a diameter to the query narrows the list quickly. Related topics include laboratory storage, sample organisers, propagation tubes, spice racks and ant keeping, which reuse the same tube format. If a result is close but not exact, the model page often links to a variant in another size.

FAQ

Perguntas frequentes

What tube sizes do these models fit?
It varies by design. Most listings state a diameter and sometimes a length, so measure your tubes first and compare them with the description before printing.
Do test tube racks need supports?
Many are printed flat and need none, but overhanging clips, angled slots and thin legs may. The model page usually says what the author used.
Can these models be printed in resin?
Small holders and bases often can, though thin walls and snap fits behave differently than with filament. Check the author's notes and photos of real prints.
How do I find a rack for a different tube diameter?
Try the same terms with the diameter added to the query, or search for related words such as holder, stand, insert or tray. Remixing a close model is also common.
