Pots to start plants for bees

My roommate has a 3d printer. I started making starter pots for the seeds I have ordered. So far I am going to be planting Anise Hyssop ( Agastache foeniculum ) and Bee Balm ( Monarda fistulosa ) . These two plants are in the Lamiaceae family of plants. This family of plants include mint, cooking spices like sage, basil and thyme .
