Plug-Filter / Filter

With nine gaps lies equidistantly on the surface
of it, the product which looks like a simple tube
can effectively filter tea out. Due to the malleability
of the material, the product can deform and be
made oppressed against the bottleneck. The
contraction distortion of the equidistant lines
could successfully prevent tea from releasing.
The model in the picture is a finished product
made by 3-D printer.
