Idesigned this for my bonsay, i used pla but then used trasparent spray paint to protect pla from wather. Idesigned also a small grille that has to be placed over the hole, to prevent the soild to spill out. Pla is pretty tender and you can easly drill holes to fix the plant to the vase with wires.

If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design. Thanks, Enjoy!
