This model is the result of a 3d scanned birch bark planter that was modified into a cup design. It's primary function would be to hold dry items (dry or fake foliage, flowers, pens, pencils, whatever). I am not an expert at planters, but for live plants this could probably be modified with some drainage holes in the bottom and feature a tray underneath. Feel free to remix!

Rather than attempt to fix every overhang, I highly recommend using “make overhangs printable” in the slicer of your choice. I am using Orca Slicer and know that it does indeed feature this option when slicing. I would not recommend using supports, as the benefit would be far outweighed by the extra print time and material usage.

For the model pictured, I printed in Gray Elegoo Rapid PLA+ at a layer height of 0.12mm. Three or four walls should be more than sufficient. Minimal infill should be required (5-10%). 

You can likely print this without “make(ing) overhangs printable” and I have done so myself with very little negative impact on aesthetics. I don't often include standard print settings with my models because I prefer to let people experiment with the settings that work best for their machine.

If you run into trouble with the print or have any questions, please feel free to reach out to me. Happy printing!
