This is a strainer lid for canning/mason jars, available for both regular and wide mouth.Inspiration came from this thing: http://www.thingiverse.com/thing:10601 and a desire to strain the liquid off of canned peaches. Useful for any canned goods, or anything else you need to strain from a jar (like kefir grains, or vanilla beans when making an extract, etc.).See http://www.thingiverse.com/thing:19105 for the lid this was based on, and for links to more canning jar accessories.This thing is a part of a collection of things featured in this post: http://www.protoparadigm.com/blog/2012/08/what-to-do-with-a-3d-printer-make-canning-jar-accessories/Download the strainer in regular or wide mouth.
