Heart shaped cat grass planter

So i have 2 indoor cats, and i've made them this cat grass planter. The top mesh prevents them from pulling out the seeds, but lets the grass grow through the holes. Should be printed with PETG or ASA

To prepare the grass in this planter, you either put in some soil and grass seeds, or use cotton balls and really stuff them in there. You spray your base with water, put on the seeds, spray again, put on the mesh and cover with damp paper towel. Spray with water daily or every other day. Keep it covered untill the grass grows. 

Hopefully you like the model. I'd appreciate likes, and also some constructive feedback.
