We like to make smoothies w/ our Vitamix using the “personal cups" which screw on to an adapter base that contains the blades. The gasket (or o-ring) on our adapter has become stretched over time and doesn't always make a good seal when the cup is screwed on to the base.
So, I designed this replacement and printed it w/ TPU. It's more firm than the original gasket, but seems to seal well enough. It's a brand new print, so we'll see how to behaves over time.
I have generic Inland TPU, so I'm not sure of the “hardness” measurement.
My gasket is printed w/ 2 wall loops, 3 top layers, 3 bottom layers, and 15% infill.
