Product Description
when produced by shapeways, this seems a bit too big, and have used 2x61 mm metric buna-N o ring from the o-ring store, clarkston WA 99403, see other gasket for more details
We made from elasto plastic which is not listed in the drop down below
to get this to display in the shop i had to list with a material, but this site does not allow choice of soft plastic which it should be made in, the soft choice is avaialble on the main shapeways ,, in our experience, it is better to use the commerical silicone o-rings above, the 3D prinited ones are a bit rough and also more fragile,, perhaps there are other choices we are not aware of
