ISO 7089 M10 STL, Plain Washer, plain flat washer, normal series

The washer is a precise STL model created in accordance with ISO 7089, DIN 125 and PN 82006 standards, ensuring full dimensional compliance with international flat-washer specifications. It is a small part with defined dimensions (10.5 mm inner diameter, 20 mm outer diameter, 2 mm thickness), easy to print without supports or special settings. Thanks to its compact size and simple shape, the model can be printed in just a few to a dozen minutes, making it ideal for quick tests. This element can be used to calibrate external and internal holes as well as external and internal walls—especially holes and edges—providing reliable dimensional-tolerance results. Due to its fast print time and robust geometry, the washer serves as an excellent calibration model that, with proper slicer tuning, enables exceptionally precise 3D-printer calibration. This allows any user to easily verify and adjust their print settings, optimizing print quality for holes and edges. Additionally, the model can be used to assess first-layer print quality, helping to fine-tune nozzle height and bed adhesion.
