Soil tank for biOrb Tube 30

cults3d

Since the whole bottom of the biOrb Tube 30 liter version consists of filter pebbles that are not so shrimp friendly, we designed soil tanks to position in between the pebbles around the middle filter tube. Also you can use these tanks for planting real plants in the fish tank. I have two of these in our biOrb sitting, technically three should fit around the middle part. The foot file needs to be printed four times per tank to have a space between the bottom of the biOrb and the soil tank. The feet clip in from the bottom.
