"What a crappy idea *giggle*. But seriously, I´d rather close the lid on the toilet and empty the brush holder more frequently. An better improvement would be to add a good way to grab and empty the holder than to have a poopwater-trebuchet sitting there for your toddler to activate. Typical "single male designer household" improvement. I would take bets on it."

"I worked as production manager at a large 3d printing service. The goods we had to ship daily also varied drastically, from 1 cm to 1,5 m in size. As cost for shipping with our parcel service was dynamically calculated based on parcel size and weight we tried to keep the packaging size close to a minimum. That meant we spent a lot of time picking the right parcel out and even more importantly we spent a lot of space in storage for the different sized parcels. We basically reduced our stock to three different parcel sizes to simplify the process, which lead to the same results: tiny pieces in overly large parcels, but sadly - cost efficient."
