We conceived this cutting pattern in order to cut our V60-01 filters perfectly. This product is 3D-printed by ourselves.
You may wonder why we cut our filters ? You may have noticed the V60 filters whether it is Hario or Cafec are symmetric but including the heat-sealed part. We cut it so we don’t end up having a side of the paper higher once in the dripper, the opposite lower and potentially the filter not exactly in the center and maybe producing an uneven extraction.
This product does not comes with filters.
