This is a fixed model of the coffin planter by VolcanoEyes

The issue with his original model when I printed it was that the drainage section (The lid of the coffin) was raised slightly, causing issues with printing and also making it not waterproof. This lowers that section to be level with the rest of the base to allow printing without supports and so the printer will actually make it water proof.
