Drip free cap

Inspire from [A better wine bottle] https://youtu.be/ydR1CsX4Fek

Although I don't really understand fluid dynamics, all I can do is copy this idea, and it works well with sesame oil and soy sauce, say goodbye to pesky drip~

30mm cap with 3 coil of 1mm screw, and a inside ring with diameter of 24mm.
Or add it with your own, 3 kind of file for you to customize.

雖然我不懂流體力學，不過把這想法拿來應用在蓋子上十分成功，香油醬油都能用，跟黏黏的罐子說再見~

30mm的蓋子和三圈的1mm螺紋，以及24mm的止漏內環。
又或者你自己改造，三種檔案供修改。
