The 2-point design idea of the cat grass planting box

The common pain point of traditional hydroponic cat grass planting boxes is that during the growth of wheat,
Odor due to anaerobic respiration due to seeds being completely submerged in water.
When users add water without experience, they will not control the water level

Excess water can flow out, but also to avoid the outflow of water wet desktop or windowsill,
The small skirt shape at the bottom can not only solve the problem of water collection, but also add a little interest to the product.

Project Date: 2021.7
Product status: mass production and sale

During the actual test of the 3D printed model, it was found that due to the narrow leakage tank, the water flow would not flow out due to the excessive tension in contact with the bottom plane of the tank.
Therefore, I changed the bottom of the sink from the original horizontal plane to a downward slope of 45 degrees from the outside to the inside, which can avoid the problem that the water level is higher than the predetermined value and does not flow out due to the tension of the water.
