A planter in the shape of a nautilus shell (following Fibonacci's spiral) for fake plants!

I glued in black foam in the shell's opening, added decorative rocks, and a fake plant (materials are available at most dollar stores).
Foam or something lightweight is necessary unless a base or counterweight (inside the print) is added.

Unfortunately, a real plant would likely not work for this planter, as I did not include drainage holes (which would have an inconvenient placement) and the dirt could be too heavy.

I designed this myself on Fusion 360 but followed a helpful tutorial on YouTube:

I recommend printing with support to help the smoothness and adhesion of the shell on the print bed.
Support everywhere is not necessary, only touching the bed.

I recommend a higher density, like 22% - 25% to keep the shell heavier and more balanced.
