Shampoo Bottle Drain Tray

My shampoo bottle always developed gunk underneath because the water couldn't drain away, so I built a simple holder with a honeycomb bottom so the water can drain away from the bottle. The interior diameter is about 98mm, so you can scale up or down for your needs. This can be printed without supports, but the inside lip will be stringy and uneven. Once the insert is placed, those irregularities are not noticeable, but if you want clean edges, print with supports.
