I had a request for a donation jar lid to keep the donations going only in one direction. Really just needed a barrier for little sticky fingers so here it is if anyone else needs one. This fits a large glass cookie jar with a 5.59 in. (142 mm ) OD diameter lid. The top lip of glass is about 1/4 thick. This design has two equal half's that just bolt together with 1/4 inch bolts and 7/16 friction nuts so a tool is needed to open. Print with the "Thanks !" up with support for a clean looking top. I used a sharpie pen to highlight the raised printing. The two arrows are to cover up the small opening on either side of the donation opening and to give a little more strength.
