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 so
