This is a 30mm dia lid for any jar or bottle. You can convert any jar as simple container. You can also use it as box or container or water gallon lid. You can 3d print whole 3d model at once, don't need to print every parts separately. 3d printable stl file attached separately. Opening of the jar should be 30mm.
