This template allows the generation of custom flat gaskets and washers.

A precision of 0.1 mm is available for each parameter: inner diameter, outer diameter, and thickness. It is also possible to add a chamfer or a fillet on the inner and/or outer diameter, on one or both faces.

The choice of chamfer or fillet helps to smooth the edges and/or improve mechanical strength.

Customizable dimensions make this generator suitable for both prototypes and functional parts.

These flat gasket or washer models can be printed in flexible/soft material or not.

3D-printable flat gasket, washer, and ring models

Flat gaskets, washers, and rings are simple yet essential components for assembling or sealing mechanical parts. 3D-printable, these elements can be easily customized by diameter, thickness, or geometry. Their parametric design ensures a precise fit, suitable for various uses such as spacing, support, or insulation.

For the most basic needs, a ring without finish offers a simple and effective geometry, suitable for tests, prototypes, or assemblies not subject to particular constraints. This type of gasket or washer can be used as a spacer or flat support in a mechanical or structural setup.

When better integration is required, a washer with chamfer allows smoother insertion and a cleaner finish. The chamfer helps positioning on shafts or housings while reducing the risk of snagging during assembly. These models are particularly suited for interlocking assemblies or rotating parts.

Finally, for applications requiring a rounded surface or increased strength, a gasket with fillet features softened edges and a smooth transition between surfaces. This type of 3D-printable ring provides good support while reducing friction. These washer and flat gasket models are suitable for a wide range of uses, from rapid prototyping to more precise technical assemblies.
