About this generator

Customizable Gasket/Seal Ring Generator is a free browser tool on MakerWorld that turns a few measurements into a flat gasket or seal ring ready to print. It is an OpenSCAD model by OP Design that runs in MakerWorld's Parametric Model Maker, so you type numbers into a form instead of drawing anything. It has been customized about 16,000 times and has about 3,700 likes.

You start by choosing a shape. The ellipse option covers round and oval rings, and the quadrilateral option covers square and rectangular ones. Then you enter the inner width and height of the opening, the height (thickness) of the seal and the wall thickness of the ring. Square and rectangular rings also take separate inner and outer corner radii. The designer suggests printing in TPU at 100% infill so the seal stays flexible and solid.

Commenters report using it on an airbrush nozzle, a leaking pool chlorinator, a brush cutter and small screw-top tubes. The listed settings include no bolt holes or rounded edges, both of which people have asked for, so it works best as a plain ring for lids, containers, tools and enclosures. You need a free MakerWorld account to generate and download the file.

What you can make

  • Square gaskets with rounded corners
  • Rectangular lid and enclosure seals
