Kikkoman sells pretty good soy sauce, unfortunately the've forgotten to design a lid for their bottle.
Not very hygienic, i've seen little fruit flies in
...さらに表示 some bottles of mine before:-(
That's why i design a cap for it, enjoy!
Beware that this design only fits properlywhen printed with flexible filament like ninjaflex or TPC!
I've printed mine with "TPC flex 45" and the lid closes the bottle absolutely water tight
