My family uses a variety of different toothbrushes and I wanted something that could handle all of them. My wife also has this habit of leaving her ring on the counter and I'm scared it will drop into the sink.
I designed this holder thru several iterations (each one attached for others who might find them useful). Has space for 3 electric brushes (or wide manual brushes), 3 normal brushes, and 4 electric brush heads. Plus room for other items (floss, toothpaste, etc.) and a ring holder.
Final model was slightly too tall so I did a scale in Flashprint from 110mm to 90mm in that one dimension to compensate.
