Cat Grass Cup

Growing cat grass is easy with this cat grass cup. This is a great solution if your cat is like mine and pulls on the grass since all parts screw together. The double-start threads make it easy to refresh the water without disturbing the grass. Please follow the cat grass growing instructions, but I have a few tips:

1. Don't overfill the cup with seeds. I aim for 1 layer of seeds, similar to the photo.
2. Change the water daily and fill just up to the bottom of the seeds.
3. Cutting the grass and roots makes pulling old grass from the container easier.

I recommend printing with 100% infill so that the cup is water-tight. The top hexagonal pattern uses an infill modifier so that you can customize the infill pattern or density in the 3mf file.

Update: I uploaded each piece as a separate STL file, including a top with the hexagonal pattern baked into the STL.
