I'm happy to share my latest creation: a simple yet stylish ribbed vase. It's made of two parts, printed quickly (2:40 h) and economical (only 70 g with 0.4 mmm nozzle) using spiral vase mode. I used two different PLAs—a basic grey and a wood-like one from Amolen.
To make it practical for flowers with water, I added an inner cylinder (diameter: 75.2 mm, height: 208 mm) made of clear PETG. You might need to tweak the settings a bit for a water-tight result (flow rate: 1.05, wall-infill overlap: 50 %). If you have a P- or X-series printer and use Bambu PETG basic transparent, I've got a profile that might help. See print profile for details.
You will find print profiles for a 0.8 mm nozzle (recommended) and a 0.4 mm nozzle.
