Jar Lid Sifter

Derived from oldwizard's upload: https://www.thingiverse.com/thing:173670. (Thanks, by the way!) Although it's called a "sifter," I actually created this to prevent my daughter's pet fish from jumping out of its temporary home. To thread onto a standard US narrow mouth canning jar, without forcing, the X and Y axes had to be scaled up by 1%.
