Jar Lid Sifter

thingiverse

I'd like to thank oldwizard for uploading their design to Thingiverse at https://www.thingiverse.com/thing:173670, which I've derived from. This sifter project took on a different purpose - safeguarding my daughter's pet fish from leaping out of its temporary habitat. To attach it securely onto a standard US narrow mouth canning jar without applying excessive force, the X and Y axes required a slight scaling up by 1%.
