Flexible Shower Drain Cover

pinshape

The original version was 40mm inside and 66mm outside and it was too small. These measure 76mm on the outside. I made them in TPU because it  is chemical resistant, is tough, and holds up well in the water. V1 - (the black one) has drain holes outside of the internal cylinder. When I installed it you could see the metal shower fitting below V2 - (the white one) has more coverage
