Flatness and Straightness Testers: 3D Models & STL
This collection gathers STL files for flatness and straightness checks, calibration test prints, and cases for measuring tools. You can compare how different test shapes reveal bed leveling, extrusion, and overhang behavior on a 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.

«Flatness and Straightness Testers: 3D Models & STL»
Models in this collection fall into a few groups: flatness and straightness gauges, calibration and torture-test prints, overhang and stringing tests, and enclosures for electronic testers. Some are simple single-piece tools, while others combine several test features into one plate or require assembly. The differences matter because a gauge checks a specific geometry, while a torture test stresses several print parameters at once.
When choosing a model, look at the dimensions and scale on the author's page, the number of parts, and whether the design needs supports. Check the material and settings the author lists, and review photos of real prints to see how edges, bridges, and thin walls behave. For a flatness tester, note how the reference surface is defined and how the tool is meant to sit on the bed.
To refine your search, try synonyms such as straightedge, feeler gauge, bed level test, calibration print, and tolerance test. Related topics include overhang test, stringing test, first-layer test, and cases for measuring or component testers. Combining a specific tool name with STL or 3D print usually narrows results to models that match the task.
