Large bore soy sauce top

I made this top to let regular Hershey style chocolate sauce flow more freely from a soy sauce bottle. The spout has an 8 mm inner diameter. This is a for a 5 oz genuine Kikkoman bottle that I got at the local Asian grocer. It has ~30 mm neck with about 2 mm threads. Printed top down without supports.

As with all things 3D printed, the nooks and crannies probably make this unsuitable for long term food contact even though the PLA I printed in should be OK.

Update: I added some material to allow a seal with a washer. This model is Soy Sauce Cap V2. I have not printed this model.

Update: I added an additional V2 model with a 3mm bore. I have not printed this model.
