Spice bottle inner cap

Not sure if this type of spice bottle is common outside of Northern Europe, but here you have it anyway... This is model for the white inner cap.
Those spice bottles/jars are tempting to re-use because you can get refillls in cheap bags, however the inner caps get lost, worn out or are just wrong type for the spice you're refilling - ie. it could be one with small holes for ground pepper when you fill it with whole peppers, or vice versa.
3D printing those inner caps is a perfect solution. N
