A box that floats on top using foam insulation you can get at the hardware store. There are no holes in the sides, as you would see in the “pond baskets” normally used in the hobby. I kept ordering baskets from online sellers and getting ones with holed to big to use with smaller species.

• The size of the holes in the floor can be customized in the parametric fusion 360 model.
• The STL included here is sized to maximize the print bed of a Bambu X1C printer.
• STL will fit into a 10 gallon  or 20L easily
