This is just a basic planter in the shape of an e3d v6 nozzle. The base should be printed with a higher infill to add more weight. The rest of the model is all press fit together, you may want to scale up the e3dv6_pot.stl file just a tad if your printer isn't spot on.
See the pictures for the part orientation.
Enjoy!
Edit 14/06/22 - I brought the screw threads in so that they had way less overhangs as well as added more of a base to the nozzle as well so it should be printable without supports. Enlarged some of the holes as well for easier cleaning, if you prefer, you can just glue the parts together. Fixed files have v0.2 in the file name, the base was unchanged.
