Simple waste bin for next to our sink. It has a slot to one side where we can put our strainer that we use to filter coffee grounds so that they do not go down the drain. The intent is to capture food scraps for later composting.

December 2025 Update

We found the original waste bin simply too large.  Also, we make our own bread and can re-use the 1 gallon plastic bread bags for a waste bag next to the sink.  So, I added an option to the OpenSCAD model to put in a bag slot next to where we put the coffee grounds strainer.  The original large bin STL is still here, but uploaded a smaller version with slots for the re-used bread bag.
