This is a replacement gasket for a square glassware container.
The F360 file is included so you can modify the dimensions to fit your own container.
Print with TPU. 20% infill. 0.20mm layer height.
4 perimeters
4 bottom layers
3 top layers (this allows the gasket to “squish” better when it contacts the lip on the container. (4 top layers was a bit too stiff imo.))
