26.6mm ear plug/ tunnel blank

thingiverse

just as the name describes. meant to be printed as two parts then glued together, i print in abs and use abs/acetone mix to glue and smooth for comfort. no supports needed. add things to the centers, make your own custom jewelry. wearable diameter is 26.6 mm, custom size for my wife, however if you simply scale size in accordance with what you want/need you'll find they sit nicely.
