This is a part of a Zojirushi rice cooker. Its purpose is to collect water that has condensed from the steam of the cooker. It is removable. Mine broke, so I replicated it. Enjoy! Dimensions are in millimeters. Piece is actual size. I printed it in PLA plastic on an Ultimaker original using Cura 15. It fits in the cooker pretty well for me. The original part has some draft, but I ignored this because I'm 3D printing it instead of doing injection molding. I don't think the draft is necessary for proper function.
